I have a 2006 gs300 with mark levinson navigation system. Recently bought a aftermarket bluetooth adapter and installed it myself. All I had to do was put it in-line to the radio and it worked perfectly.. Except! Nothing else in my car works! Windshield wipers, automatic headlights, mirror tilt, a/c controls, seat memory settings, mpg meter, temperature outside, headlight leveling... Nothing! And I can't get it out of park without using the manual override button. Now I have the tire pressure sensor light on along with p/s, brake, check engine, abs and it was saying check headlight but that has gone away. I've tried resetting the ecu multiple times and driving it and nothing has changed. I consider myself a mechanically inclined person and I'm just stumped. Dealer is not an option rite now and I'm willing to do almost anything to fix it myself. Any help is appreciated

Check the main fuse in the fuse block, you might have blown a main fuse when you did the install. Its the 150amp fuse

Djallday

what fuse block would this be in? the only 150a fuse i fould was by the battery labeled "ALT" is this the one?

I would just check ALL of the fuses.

Djallday

checked all of the fuses in all four fuse boxes and all of them are good. this is driving me crazy

Dumb question did you remove the unit and see if it all comes back? If not consider it, this will help you retrace any harnesses you may have plugged or unplugged to install your BT device. What brand is the unit?

Djallday

YES, i drove about 30 miles with it in and then removed the unit and drove another 30 miles or so to see if it would reset the ecu but no luck. nothing has changed since. hooked up obdII reader to it and no codes came up either.

you said checked all 4 fuse boxes, can you specify the locations?

Did you remove the harness and everything? Remove the harness too if all you did was unplug the device... my guess is the harness has a wire or two at the wrong pins (sounds like you said it's a pass through type).

Reason I suspect you didn't remove the harness and just the device is because of laziness of not wanting to remove the whole dash unit again - the same reason my harness for my GROM is still on the car even though that stupid thing bricked completely on the last update I tried to do to it.
