Radio gremlins

Does anyone's aftermarket radio with a PAC onstar adapter randomly not turn on when you start the truck. When it doesn't turn on I just need to turn the truck off and back on, them boom radio works normally.

Had this issue since I swapped my first aftermarket in 3 yrs ago and I'm finally fed up with it.

Yep, I have it. It seems that the PAC unit doesn't always receive the signal from the data bus. I am in the habit of leaving the switch in the on position to see if the radio comes on. If not turn it to off and back to on. This usually clears it up.

I notice weird behavior with the chimes (if you added that module) that I get a double ding when turning off the truck.

I tolerate this behavior because I could never get rid of the alternator noise in the Metra module.

I cut the power wire to the chime speaker. Drove me nuts

Yea I too ditched the chime speaker. Beeping for open doors and seatbelts piss me off. I always close the doors and put on my seatbelt but the chimes would still piss me off if I am driving slow with my head out the window listening for noises during diagnosis driving around the block.

I also had the issue with the head unit not turning on but it's very infrequent. Usually once a month or so. I either turn it off and back on or hit the phone onstar button which kills the power to the unit then kicks in the onstar then push the phone button again to turn on the head unit and that also does the trick.
