Ginkgo USB-CAN Part 6

Posted 04-19-2019 at 10:48 PM by Indymaynard

Super exciting!

I now have several codes that have enabled me to play audio from another device via the amplifier in my Jeep! So, Boston Audio premium is not what the interwebs cracks it up to be. It has a left and right input for audio on pins 18, 19, 20, and 21. This is a deceiving label, as the front speakers are also connected to this. The important part of the whole system is the amplifier. This may seem obvious, but I'm also kind of dumb. The amplifier takes care of the fade and volume, but you are still stuck with only the right and left channels with some fade from the amplifier. Not to worry! That's really all a vehicle needs, in my opinion.

The CAN code, for any Jeep or Chrysler owners that share this encoding, is as follows:

Code:
3D0  00 0A 0A 0A 0A 0A 00 - Definitely amp on
     01 0A 0A 0A 0A 0A 00 - Radio on, volume 1 (0), bass middle, mid middle, treble middle, balance middle, fade middle, last octet is volume up to 26
I beg you to chalk any typos up to alcohol. Other codes you might need are:

Code:
09F: 01 13 BD 1F FF FF FF CF
43E: FD 3F BF FF FF FF FF FF
3F1: 41 00
3D0: 09 0A 0A 0A 0A 0A 00
I didn't toggle any other CAN codes on this one, so I know this combo works with my setup. Once again, my setup is the 2007 Jeep Grand Cherokee Limited with the Boston Audio "Premium" setup, though mine did not have the front speakers in the configuration that is commonly shown on the internet. Still, I was able to get it working, and that is a huge plus.

Lots of views on this, but no remarks or questions. It would be awesome to not duplicate efforts somewhere.

Cheers!
