my issue is, every single time i shut my H2 off, my radio will flip through all my presets until i open the door. this is caused from the steering adapter..

is this a common issue with the adapters, or is something fubar(most likely)

Sounds like the programming on the steering wheel adapter may have gone haywire. As you know GM vehicles use the exit music feature that allows the radio to play for up to 10 minutes after the key is turned off and removed. The manufacturers of these adapters included that feature. It sounds like that part of the programming may have been corrupted.

The newer models are computer up-dateable, meaning they have a USB connection on them to allow the software on them to be updated. Depending on what is inside your install, it may just need to be reprogrammed or replaced. Either way someone is going to have to take it out and troubleshoot it.

It also may be as simple as just resetting the adapter as well, again though you would need to take the dash apart to get to it. You may want to take it back to the place that originally installed it.
