Thread: Metra GMOS-04

Has anybody had a problem with this after it was installed? I had it installed with my Pioneer AVIC-D1 in my 06 GXP and it was killing my battery. I read a bunch of bad reviews on Crutchfield's website about it, and was wondering if there is a better option.

i have one in my 04 and from what i could find there was no reliable option if you wanted to keep the door chimes and all the other alert signals in the car. but i've had no problems with mine so far.

Thanks guys, I guess i'll try another one. It seems like these things are hit or miss.

I was originally using the gmos-04 and have found that the peripheral gmach24 is much better (more versitile) down side is you have to buy a seperate charms module
