Thread: Aftermarket Stereo Problems?

go to best buy we sell the adapter so everything works like it should for about 110 . it retains the dome light supervision , door chime and most importantly parts of the instument cluster . i cant say enough especially gm vehicles after 98 DO NOT cut the harness , most gm went to no switched voltage behind the radio after 98 and then the dreaded onstar , then rds , then amps , so that one harness does alot

Thanks for the info!

My friend wants me to install an aftermarket radio into his 2005 GP and best buy told me you need to keep the stock radio in the car (they say they relocate it to the trunk) to keep the door chimes and stuff. Is that true or will this harness from best buy do all that without having to move the stock radio into the trunk? And I believe he has the monsoon.

I work at bestbuy as well, its going to depend, theres actually a few ways to install a stereo if you have the monsoon or the bose, since i have a 2000 gp mines the bose, but its a similar situation. Yea you can relocate the stereo to the trunk to keep the chimes but thats kindof a waist of space unless you constantly forget your key in your car, forget to shut your door, or leave your lights on (grand prix's have constant running lights so that shouldnt be a problem). Ohh and the most annoying the seatbelt off chime.

If you want to run without the chimes a harness adapter will do ya no prob just make sure to check your connections, if you have a factory amp and i cant remember if the monsoon does, the bose does. You will have to splice the control wire into the remote wire on your aftermarket deck. Works just fine and i didnt lose anything but the most annoying chimes that i hated anyway, surprisingly enough i kept the open door chime and the key in chime.

If you want the chimes the easiest way to make sure you keep them will be a gmos-04, ide sell you mine but the only one i have is the gmos 01 off my buddys old malibu and that wont work on yours. Either way the gmos04 is about 100 bucks at bestbuy. Itll retain his chimes and if he wants even his onstar if he has it.
