Hello everyone, hope you guys or ladies can help me. So I have a 2003 G35 and I notice on my alpine deck the radio reception is horrible like I can't get my local radio station some times and there constantly coming in and out. Does anybody know how to fix this or if it can be fixed. And my apline deck is a alpine cde-w265bt. If that's help at all well please get back to me any thank you so much

 

I got an aftermarket antenna installed on top of the windshield and it helped get better reception but still not perfect

 

Oh really. Man that sucks I'm hoping if I take the deck out maybe the attenna is disconnected but from what I'm reading they just have weak signal. But do you by any chance know where the attenna is on an 03 g35?

 

The antenna is somewhere in the rear deck by the back windshield

There is a powered in-line antenna amp which could be part of the problem... Good luck.

 

After the install he likely didn't use the extra power to the antenna like your supposed to.

 

It's actually in the rear glass. Lower left IIRC.
