Tuner Gremlim

I replaced my Factory NAV unit with a single DIN Pioneer unit and steering wheel control module. A month after installing it the tune volume would jump from 14 to 40 in a split second, but the volume level shown on the unit stays at 14

When I tried Crutchfield's tech support they said they have had problems with the Pioneer units and sent me a new one. A month after installing the new one, the exact same problem came back.

Now Crutchfield is saying it may be the steering wheel module. Has anybody else had this problem?

Yea I would say it's the module as well. Which one did you use?

Turned out to be a bad plug on the steering wheel control module
