I recently got the Kenwood Dnx5140, installed it in my Monte Carlo but all I get is a red blinking light in the top left corner, screen won’t turn on or anything, also do I have to have the GPS antenna hooked up in order for the unit to turn on??

you give some good clues. because your third brake light works but not the other two, and because you sometimes get brake lights if you have turn signals on at the same time, i would say that some wires got crossed up with your other taillights. check out the power wires back in the taillight assembly and the wires that run back to the taillights. something is mixed up back there, now you just have to find it. if all else fails after you isolate which wires are the brake light wires get some new wire, same gauge and roughly same length, remove a bit of insulation but don't cut the wire in two, and put the new wire in as an overlay. if having the new piece of wire there makes the brake light work you found the break in the wire. you can cut out the bad piece and fasten the new piece in. you can solder it if you have the equipment to do that, or you can buy some squeeze in place connectors at the car parts store. either way, good idea to tape it up when you are done. hope that helps

try pressing the hazards on and off if they still don,t work replace the flasher unit. it is built into the hazard switch( all one unit ) change this and all will be good.

I had to replace the turn signal switch in my 1998 z34.Now everything works fine.

Sounds like it is going off track whenever it gets to the popping sound point. Or its catching against something, Check to see if anything could be in the tracks of the sunroof. Hope this helps, James Booth. Let me know what happens
