Custom Proxy for UConnect 7", 2 x USB and CarPlay Retrofit

[JStrongy]

Hey guys...

First off, been a long time reader but only just registered. Reading through the posts on here, have been invaluable!

I have a 2015 500X which originally had UConnect 5" and USB+AUX module.

I've retrofitted a UConnect 7" and 2 x USB+AUX then run a Proxy Alignment - all ok and milage no longer flashing.

Finally, to get CarPlay running I have read that I need to extend the Proxy to 235 bytes and then made the below modifications:

Byte 148= 05 (Uconnect 7)
Byte 157= 01 (CarPlay)
Byte 160= 01 (Android Auto)

My current Proxy is:

Code: Select all

33 38 33 33 34 30 31 30 36 30 31 4F 55 54 50 55 54 2D 53 49 54 20 15 06 09 47 00 20 05 00 00 00 00 02 00 00 00 00 00 00 00 47 00 20 05 00 00 00 00 02 00 00 00 00 00 00 00 D9 FA 0E 02 AC 82 07 E2 50 27 89 07 40 10 10 03 A3 28 54 92 01 35 73 14 01 4F 03 34 00 B3 A8 01 49 03 07 00 A2 00 0D FB 00 00 10 01 00 05 03 54 91 05 02 AD 00 52 00 01 8A 13 3D 40 00 05 03 C5 00 D1 24 10 00 00 49 02 81 12 79 42 80 00 00 8B AA 95 71 20 80 80 85 00

The new custom proxy would therefore be:

Code: Select all

33 38 33 33 34 30 31 30 35 34 35 4F 55 54 50 55 54 2D 53 49 54 20 15 06 09 4F 04 20 05 10 00 00 00 02 00 00 00 00 00 00 00 4F 04 20 05 10 00 00 00 02 00 00 00 00 00 00 00 D9 FA 0E 02 AC 82 07 E2 50 27 89 07 40 10 10 03 A3 28 54 92 01 35 73 14 01 4F 03 34 00 B3 A8 01 49 03 07 00 A2 00 0D FB 00 00 10 01 00 05 03 54 91 05 02 AD 00 52 00 01 8A 12 3D 40 00 05 03 C5 00 D1 24 10 00 00 49 02 81 12 79 42 80 00 00 8B AA 95 71 20 80 80 85 00 00 00 05 00 00 00 00 00 00 00 00 01 00 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

I've read horror stories on these forums about custom proxy's bricking cars, so just wanted to post here and someone give it the once over, before I run it!

If someone could, that would be much appreciated!

Thanks in advanced!

Can't spot any problem. I usually start with a proxy lengt of 193, if the car does not accept that code then I try 235

There are others out there wih more experience and knowledge than me but have done quite a lot of cars.

Perfect, thanks for the advise - will give it a whirl tomorrow starting with 193 bytes.

As per your advise @barthmultijet, I just extended the Proxy to 193 bytes, made the changes I quoted above and the car accepted it.

Very happy to report that CarPlay is now working!

Below was the final Proxy which I used:

Code: Select all

33 38 33 33 34 30 31 30 35 34 35 4F 55 54 50 55 54 2D 53 49 54 20 15 06 09 4F 04 20 05 10 00 00 00 02 00 00 00 00 00 00 00 4F 04 20 05 10 00 00 00 02 00 00 00 00 00 00 00 D9 FA 0E 02 AC 82 07 E2 50 27 89 07 40 10 10 03 A3 28 54 92 01 35 73 14 01 4F 03 34 00 B3 A8 01 49 03 07 00 A2 00 0D FB 00 00 10 01 00 05 03 54 91 05 02 AD 00 52 00 01 8A 12 3D 40 00 05 03 C5 00 D1 24 10 00 00 49 02 81 12 79 42 80 00 00 8B AA 95 71 20 80 80 85 00 00 00 05 00 00 00 00 00 00 00 00 01 00 00 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00

Thanks again!
