A customer has a 01 escalade. I installed a panasonic in dash screen. Instead of using a peripheral adaptor, I want to convert the On-star audio signal to RCA and run it to the aux in.
The cady has the GM old school adaptor on the HU. Im thinking the On-star audio wires are blue/blue-blk...and browns..
Someone impress me

 

PAC and Soundgate both make onstar interfaces for that year

 

still need a starmod1

it will give you an audio output you can use

 

do you know what the factory on-star output is? and what does that adapter do?
It doesnt look like it has class 2 data on that HU, The customer is dropping the truck off on friday, Ill try a few things
nice to see you back shaughn!

 

I looked up the instructions on the PAC interface. The brown is supposed to mute the radio while onstar is on, you could use that to trigger your aux input, it's called INT (interupt) on my alpine. The instructions don't say what the audio is from onstar, but you'd think that would be traceable. You'll probably need a LOC to change it to RCA'a and adjust the levels.

 

thats exactly what im thinking, Im hoping that i can use the internal output ajust, (SLA on pioneer) to level match

 

well, I got it beat. I use the grn/white and brn/white as signal pos. and blk/white as signal grnd. I fed it into aux2 and got full onstar thru the aux 2 channel.
Thanx for the info..
