Hello veryone. i have been having ossues with my radio (the whole unit) not wokring. when i start my car up it turns on then shuts off. anybody have an idea what it would be. been thibking about testin if power is.coming thru

 

Definitely start by checking for 12 volts at the headunit (radio). If the 12 volts is there when the headunit is not working, connect a ground wire to the headunit. If still no sound, the headunit is bad.

If you need to ask more questions, we need to know:
1) year of your car
2) Bose or non-Bose radio
3) factory navigation or not

 

2005 maxima se. factory navi radio and yes bose.
it only lights up. when i ubplug the negative from battery and back on it trns on

 

bump someone help me

 

Have you hooked up a ground wire to the metal case of the head unit? Unplugging the battery cable sounds like the electronics has gotten "locked up" and unplugging the battery cable resets it.

I hate to tell you this, but if all you get are the display lights and no sound after you unplug the battery cable, I think the head unit is bad.

 

i have not

 

should i ? u think its a loose ground? only after reseti the system is when it stays on til i shut the car off

 

Try that ground wire. It doesn't cost anything. But I am still thinking the radio is bad.
