I don't have the 32-pin connector anymore as I ripped out all the RNS-E internals. I'm running a Pi with a CarPiHat Pro DAC, with the 3.5mm output wired directly to the line out pins on connector C (pins 3, 5, 8, 9, and 11) on the quadlock. I'm trying to feed audio from the Pi directly into the car ...

Sorry, didn't see there was a second page. I have the audio going directly to the line out pins on the quadlock connector. I don't believe I have the 32-pin connector anymore.

I have the 3.5mm wires going to C3, C5, C8, C9, and C11 on the EXT Control Connector

Thanx!

If it can help other people with CarPiHat, I just cut soldering trace in "Can Terminal".

Hi, I ...

I am very interested in this. Currently, I am doing a similar thing in my B6 S4 and B7 A4. I ripped out all components of the RNS-E, installed a touchscreen display, a Pi5, and a CarPiHat Pro 5, and wired the hat to the head unit connector. Is this similar to how you approached yours, or did you ...
