Ive kinda read up on this but id rather get some input for my exact issue.
My 04 g35 Sedan has a problem where if i accelerate to fast, brake to hard, turn to hard or tap on the console the radio will cut out one side or both. Seems to be fine if ive got it fixed by the time i stop i can sit and play without issues and it only does this for cd player any help would be great. I plan on taking out my radio tomorrow and would love to know what to look for as far as loose wires/ messed up circuit board.

 

Most likely it's your battery. May need to replace it, but it could also be faulty connections... My vote: battery

 

Battery...really?

There's a huge problem with the Bose headunits and the CD player. May as well start looking for a JDM double din kit and an aftermarket radio now.

My entire CD player stopped working, and will not eject the discs that are in. Displays only "ERROR F0" when I choose disc mode.

 

Well i decided to take it apart and take a look and now my car wont start i remember reading that this happened to someone else but i can find the post and id love some help with this i got to go to work tomorrow

 

Having a problem accurating and using your sterio huh? I don't know much about either, but I may have some advice on fixing your stereo...

My issue was quite similar. The thing that perhaps most often goes wrong with these head units is the connection of a small ribbon cable on the bottom of the head unit. The wires are thin and sit along the bottom of the dash so that bumps etc. will cause the connection to go in and out. The cable is soldered so if you're better at soldering than you are spelling, you could go that route. If not you would either need to buy a new HU from a junker or on ebay and cross your fingers you don't have the same problem again. Or do a double-din conversion like most of us.

You're probably thinking "Who cares about my sterio, I can't even start the car!" Well that is a little less obvious. Check your connections to the battery. Did you disconnect the negative terminal when you took out the head unit? You may have drained the battery in the process, I did the same to my last car while changing out the stereo.
