Morning all. Having a bit of a problem with my non Monsoon Radio in my 07 H3. A search of the forum leaves me to believe that Vehicle is haunted. At any given time when I turn on the radio I have a 50/50 chance that all of the speakers will work. Combinations include, Just rear speakers, just front door speakers, just front tweaters or a combination of all three.

Pulling fuse and disconnecting battery also has a 50/50 chance of working. Any ideas? Thanks in advanced.

Perplexed in Pensacola

 

I had a problem with my factory 07 navigation screen that would flicker.
I found my problem to be the 24 pin (grey colored) connector on the back of the head unit.
This connector also supplies all the signals to the speakers. This could be your problem too.
I put carbon conductive grease in the female harness connector and wiped the face of the
connector clean and then replugged it into the head unit.
it has been months now and no problems.
I believe you have the same connector too. Give this a try, it is inexpensive and may work.
good luck
