Hey guys I just installed my alpine CDA 105 in my car. All seemed to go right until I decided to take it for a test drive. On the test drive the I noticed that my head unit will turn on and off just cut in and out. So basically I turn my signal lite on and the head unit shuts off. and about 20-30 seconds later after the signal lite is off the head unit turns back on. What is the problem here I am totally stumped.

I used the PAC module interface and harness to install if that makes any difference. Everything worked good until I started driving it.

 

What year and trim is your car?
What is the model # of the harness and interface you used?

 

well its a 2005 Pontiac Pursuit 4 door sedan. with no on-star or no pioneer sound system. Its just the base model. The Pontiac Pursuit is basically a re badged cobalt. instead of Chevrolet badges its Pontiac. they look the same and they are basically the same. and the Module/interface that I used is PAC C2R-GM11b.

 

sounds like the interface is busted

 

i had this problem with my 07 ss and it was the pac black box that was doing it install went all fine till i left the parking lot and turned my turn signal on and the headunit would shut off like yours is so i took it back and they swapped the pac box out for another one and it worked fine after that

 

my installer tapped mine into something that auto dims and would only work with my lights on

 

^^^ that sounds shitty

 

Yea they always find some way to **** up something simple

 

LOL... damny brick made my night with that comment
