Rate this post


The unit and the set up course of is similar for each the A3 and A4 fashions.

BHPian prateekchanana not too long ago shared this with different fanatics.

Lastly, after dinu2506’s thread of including CarPlay to his Audi A4 B8, I gave up on the temptation of including it to my automobile as effectively. I’ve been doing a whole lot of analysis since I bought the automobile and I lastly determined to go the DIY route and provides it a shot myself first and if I fail will attempt discovering a third-party installer.

I started with the next instruments:

As I discussed I used to be on the lookout for this improve virtually for the reason that time I purchased my automobile, and with each new automobile getting this as normal, this made me miss it increasingly. Earlier than this, I’ve connected a magnetic cell holder to the windscreen and use it for navigation. Though this works advantageous, having the maps displayed on the automobile display makes it a lot extra cleaner. Not having CarPlay is the one most characteristic I’ve missed most on my automobile since day 1.

I researched this for the reason that days of fine previous Aliexpress and there have been many sellers promoting these bins for all vehicles from BMW, Audi, Lexus to Toyota and extra. Upon researching extra got here throughout a model referred to as Joyeauto which is legendary for this. There are lots of manufacturers /web sites internationally which promote these bins with their very own interfaces and boot emblem like RSNAV, Carsgadget and even Evoretrofits in India which a fellow BHPian used. If that they had their outlet in Delhi I’d most likely have gone to them as effectively for the benefit of doing issues.

Doing all of the analysis I got here throughout a model referred to as Highway high which was out there on, Aliexpress and had even their very own web site. Their field did the identical factor and was less expensive as effectively in comparison with different manufacturers. Noticed their evaluations on Amazon and at last ordered instantly via them. They gave the choice of delivery by way of DHL or India put up. The day I positioned the order they requested me to share all of the automobile mannequin particulars and pictures of the centre MMI display, together with the dashboard buttons format and software program info. Shared the identical and so they shipped the field 2 days later. I selected DHL and the field reached India and was delivered to me in 4 days flat from the date of delivery. DHL guys had been very proactive and so they collected all customized paperwork even earlier than the field bought shipped for fast clearance. They shared the hyperlink of the quantity of customs responsibility to be paid as effectively on-line. The field bought delivered the identical day to me once I paid the customs responsibility.

The field was delivered on Thursday and my weekly off was Monday so I waited for a similar to begin putting in it. Meantime I reviewed all of the paperwork that got here with it and for some purpose, they despatched the information for putting in it in A3 B9.

Upon contacting them over e mail, and even a WhatsApp quantity they supply informed me that the set up course of is similar for A3 & A4. I had seen many movies of the set up of this field however might solely discover one particular to A4 B9. I additionally discovered that every field comes with some toggle switches which must be turned on or off based on the precise mannequin and options of the automobile. As per them, I had to make use of the identical configuration as A3 and activate solely the primary three toggles as seen within the pic beneath.

I discovered one other set up hyperlink from the RSNAV web site in type of a PDF file which gave very detailed set up directions in addition to particular toggles to be turned on and off for every of the Audi fashions. Connected screenshot for a similar beneath


As seen from the above image for putting in in A3, the primary three toggle switches have to be on, the identical which had been talked about within the booklet I acquired, however for A4, the third swap must be off and the 4th must be on. RSNAV has excellent evaluations and a really energetic person discussion board so I adopted this sample of the toggle switches in my field as effectively.

All of the views I had seen said that the glovebox is held by 4 screws and I believed that ought to be straightforward to take away and a 10-minute job. However boy I used to be flawed. A few movies I noticed of A3, moreover additionally required removing of facet panel close to the glovebox with a pry instrument and eradicating an additional screw there, so I used to be able to take away that additionally. I began by eradicating the 2 screws exterior the glovebox within the footrest space first. They got here off simply and had been straightforward to take away with a screwdriver.

Then I eliminated screw numbers 3 & 4 contained in the dashboard. Noticed screw quantity 5 there and eliminated it too and the dashboard was nonetheless caught. Eliminated the facet panel and located screw quantity 6 and thought it is performed however no. I began seeing round and located 2 extra screws (7 & 8) contained in the glove field simply in entrance of the pinnacle unit and eliminated these two as effectively. Now the left facet of the glovebox got here out but it surely was nonetheless caught on the correct facet. To my shock if discovered the ninth screw which was probably the most tough to take away as there was no area to make use of the screwdriver right here. Under is the pic highlighting all of them. Needed to manually flip the screw with the little screw holder positioned on the screw and rotating it with plass. (That is the place the plass was used).


It took me an excellent 45-60 minutes to take away all of them. Lastly, the glovebox got here out and it had 2 cables inside, plugged for mild and cooling which I didn’t take away and left the glove field within the foot space on high of a field ensuring that the cables aren’t getting strained even somewhat bit.

Now the following step was to take away the MIB head unit, which is held by two screws based on the movies I had seen. Though I might find and take away these screws in 5 minutes, for some purpose the pinnacle unit refused to come back out.

These screws are situated pointing upward and had been fairly straightforward to take away as soon as situated. I attempted finding extra of them and took some photos to search out them it was not straightforward to look inside there. The frond-end had 2 crosses with white ink and what appears to be like like two damaged screws.

Lastly, the pinnacle unit got here off and it was held by a few clips and it took some effort and drive to take away it. I used to be afraid of making use of an excessive amount of strain as I didn’t wish to break something so took it out very slowly. I additionally saved wanting round for extra screws as I used to be afraid I’d discover extra of them within the Indian spec automobile similar to the glovebox. Fortunately there have been solely two of them and the pinnacle unit got here out.

After this, I seen the wires behind it are too brief to maneuver it a lot additional. The movies I had seen had for much longer wired and so they might simply place the unit of their laps. The 48pin harness is held down by a clip and I had seen the identical being eliminated many instances within the video and I might take that out. Under is the picture I took earlier than eradicating any cable from the pinnacle unit simply in case I have to put every part again the identical as the unique.

The movies talked about three similar-looking cables behind the MIB head unit, certainly one of which is LVDS (largely gray) and wanted to be eliminated and linked to the automobile play field. My head unit solely had the 48 pin harness, one pink cable and one white cable. There was a vacant yellow slot the place no cable was plugged in. Upon seeing this I used to be somewhat frightened that possibly the automobile won’t help it as just one pink cable was there and one empty slot. I went forward with the one cable that was there and assuming it was LVDS.

I used to be in a position to simply take away and fasten the unique 48 pin automobile harness within the supplied cable however was not in a position to put the brand new harness connector behind the MIB unit even after a number of tries. Because it accommodates a number of pins, I made a decision to take away each the LVDS and white cable and took the pinnacle unit out. That is the way it appears to be like.

It was a lot simpler to place the brand new cable within the head unit now and put up that I linked the LVDS cable as effectively. One finish of cable went contained in the MIB unit, one finish contained in the vehicles unique connection and the third finish within the automobile play field. The identical connection sample was adopted for the 48 pin harness as effectively. Under is a picture from the person information I acquired of the way it appears to be like.

In spite of everything this, I linked the next cables within the automobile play field:

  • Third finish of the cable coming from 48 pin harness
  • This finish of LVDS cable
  • Wifi cable with an antenna that may be caught on or left contained in the sprint. (ought to be refrained from metallic for finest sign energy)
  • USB connection cable.

Lastly turned on the automobile to check the system and it labored in a single go. The efforts had lastly paid off and I could not have been happier. For audio to work, I would like to pick AUX in media. The entire methods have this requirement. For older vehicles, they even ship a cable for AMI to aux for the system to make audio work. The cable got here with my field too however is ineffective for me.

After this, I’ve to long-press the media button for 3 seconds to show the system on and it requested me to select from CarPlay / Android Auto/ YouTube/ digicam and a few different issues. As quickly a I selected CarPlay, the CarPlay display got here up and it routinely requested me to allow CarPlay over WIFI. I enabled the identical and eliminated the cable and the automobile play was nonetheless working. Tried taking part in music, give a Siri command and each labored like a attraction. (Must maintain aux chosen because the supply for this method to work.)

For the reason that starting of my hunt for this CarPlay retrofit answer, I didn’t like the thought of a cable operating via the A-pillar to behind the rearview mirror for the mic to work because it was performed in dinu2506’s automobile. Though he urged it is barely noticeable I used to be not snug with this and I came upon that the newer automobile play bins use the vehicles unique Bluetooth mic and do not want any extra mics to be positioned. This was an enormous aid for me.

I seen the Wifi antenna was not plugged correctly however the wi-fi CarPlay was nonetheless working. (most likely as a result of the field was nonetheless out within the open). Plugged it again once more and positioned it behind the AC controls.

Now that every part was working, all connections had been performed now got here the final step was to position the field behind the MIB unit. it took me half an hour and I attempted all attainable locations I might but it surely merely refused to go in correctly at any open area. A few locations the place it went partially in didn’t enable the glovebox to be aligned correctly. After giving up on this I made a decision to let the field keep contained in the glovebox and route all of the cable from a dummy plastic which was straightforward to take away. The cable appears to be like like beneath within the glovebox. Have eliminated the seen it is beneath and on the left facet of the unique MMI unit which is seen on the time of taking the beneath image.

That is the one gripe I’ve left now with putting in the field myself that I couldn’t place behind the glovebox. I did not attempt to apply an excessive amount of strain/drive as I used to be afraid of breaking something inside. Additionally within the brief time, I used the CarPlay perform the unit bought somewhat scorching, so didn’t wish to maintain it too near another half behind the glovebox the place it cannot go warmth correctly. The great a part of it being contained in the glovebox is I can flip the a/c on and it could actually stay cool whereas working.

Lastly examined every part as soon as once more earlier than placing the glovebox again and it was working completely advantageous. Took 15 minutes to place all of the screws again, due to screw quantity 9, which took the max time. Connected is one other image of it beneath.

As soon as once more tried all of the capabilities together with Maps/ Siri / Telephone name / Music and every part is working like a attraction. Cannot wait to take the automobile now for a protracted drive and use the automobile display for navigation and music as a substitute of the cellphone. Price a fraction of what I’d have needed to pay to any third occasion together with evoretrofits for set up. However then the benefit of getting this performed by professionals with out having to fret about connections additionally is part of that value. Attaching a few photos of the gadget in motion of the brief journey I took to check all of the capabilities.

The field works very seamlessly for instance once I swap to reverse, the digicam comes up and switches off again to CarPlay as quickly as I swap to D. Additionally the cellphone connects routinely each time I activate the automobile with out having to change to AUX or holding the media button to make use of CarPlay. It’s saved in reminiscence and works routinely after about 5 seconds or so. As it really works wirelessly the cellphone can keep within the pocket or contained in the handrest with plugged into USB for charging.
