    Well if auxiliary input is what you need, you should have read my posts before going aftermarket. I have solution to AUX input ANY Seville/Eldorado/Deville/Catera ‘96 to ’03.
    Just connect the data wires together at a minimum to close the network gap (although the network is designed to work with one missing device per network loop). The data wires are the ones connected to pin E6 and F6 on HU connector (and yes are purple, so do other wires thus don't go by color go by pins). Personally I would go back to OEM.

    Here is how the network works (imagine a circle that starts with device A then goes to B then to C then to D and back to A again (each device has two wires can not be called IN and OUT does not works that way). Now imagine removing device B, in that case any of the reaming devices are still connected to the network, is true A is no longer connected to C because B is missing but no biggie since C is still connected to D witch in the end is connected to A. But now remove device D from the network (you might need to use a pen and paper to understand better). Well in this case you just completely insulated device C from the network (nothing connects to C anymore). Your car has about 3-4 of these A-B-C-D…-A loops connected together to a common point witch is your diagnose port.

    I agree you can do this replace your factory in you trunk, make a harness for you poineer run your constant and ingiton to a fuse rationg that's the same the radio requires and run new speaker wire on the ground find a good piece from the dash boards frame should be good. I've seen these new radios in caddys and the newer the car is bigger the pain. Your cars happy your happy

    This is the problem and i GUARANTEE if you listen to me you will solve it. DO NOT GET THE METRA GM0S-06 harness for aftermarket stereos. Get the PERIPHERAL GMAH-32 instead. Anybody saying the METRA harness isnt the problem has not done their homework.

    The Metra isn't an interface at all. It's a line leveler wired to a GM 32 connector. The data bus lines (E6 and F6) are shorted together.
    I will give them some credit though. They picked up the serial data for their steering wheel interface to work. If they had only taken that concept and applied it to the GMOS line to answer SOH messages all would be good.
    The PAC takes the voltage drop across the resitors in the Comfort and ent. interface.
    Peripheral does not make an interface for the Eldos. Bummer.
    If the PAC does not work as expected, I will be hacking one these boxes.

    Except I believe this Cadi has the same stereo as I do in mine, which there is not yet a direct solution for. 04 Deville Base, no Bose, no tape? http://www.cadillacforums.com/forums...e-no-tape.html
