Thread: Need Alpine wired remote control pinout.

FordNoMore thanks heaps for the alpine codes and the guide.

i ended up programing an arduino to take the input signal from my commodore steering wheel buttons and sending them through to the alpine head unit. it all works a charm but there are a few commands that i wish i knew the alpine codes for.

at the moment all the buttons do what they say but a double press on mode is source on the alpine.

i will attach my arduino code soon.

I would love to see your code and how you got this to work.

if you have questions just ask.

FordNoMore and JC_JC nice work. You guys rock! I installed a JVC KD-AVX77 in my Porsche 911 (993) a few months ago that had a Sony radio with a converted tiptronic steering wheel that I had modified to the Sony wired remote frequencies for volume and tracks.
I want to change the steering wheel over for the new JVC stereo and realize after seeing this that I’ll need to create an interface like discussed in this thread. From what I understand is that the new remote jacks for JVC, Alpine, and Kenwood are now sending digital signals instead of interpreting frequencies.
The first thing I’ll have to find out is if the signals are the same between JVC, Alpine, and Kenwood. The second thing I’ll need to find is someone to code a PIC as I don’t have anything to do this although it doesn’t look that expensive to get a programmer. I’m guessing this is a PIC16F84. This would also be a first for me so I was wondering if anyone here could help me out on this venture.

Hi all.

I know that this is a kind of bump of the old thread but I have searched for codes for my Alpine CDE-9880R and have founded this thread.

The idea is to do interface between Peugeot 406 steering wheel controls and Alpine but these codes from FordNoMore have worked a bit, not all of them, but I got idea to build Arduino code scanner for Alpine.

I'm sure it can be used for other HU's as well.

Here is a link with pictures, sketch (source code) file, codes that I have founded and description for everything.

If you have any questions I will be happy to help.

In other words use the remote as the interface. Makes total sense and simple too. I'll give it a go.

Hmm, that might be true, but I think it's a bit more complicated than that because I have found several combinations for same function as well as some functions that doesn't exist on IR remote.
