Problem with aftermarket head unit
I bought my 2002 BMW 325ci with an aftermarket Pioneer head unit already installed but no steering wheel control module. I decided to install one myself. Got everything hooked up with the battery disconnected, reconnected the battery, programmed the SWC unit, and everything worked great.
Then I made a mistake. I forgot to disconnect the battery before pushing the wiring harness and head unit back into its slot. As I was doing so, I heard some odd noises and then the sound cut off. Head unit was still getting power, just mo sound. I kicked myself for not disconnecting the battery and proceeded to check all fuses. No blown fuses in the glove box or on the head unit.
After checking fuses, I tried to turn it back on and now there is no power to the head unit.
Fuses 7 and 41 are good, tried switching with others.
Please help. Did I fry something? Hidden fuse somewhere?
Help is much appreciated.
