Just got mine installed yesterday and the unit has a couple of times now kinda went nuts and would just start cycling/changing through the sources randomly. The first time it happened (on the freeway) after a few minutes of it I was able to take control again. This morning it happened right after starting the vehicle and continued until we shut the car off (about 10-15 minutes). But it was fine when we came back out and went home.

It is a F90 BT, Sirius Tuner, HD Tuner, PAC Steering Wheel Interface and it has the hardware bypass.

Any ideas, hints, suggestions?

Quite possibly PAC getting stuck... Can you try disconnecting it and seeing if it keeps happening?

will try that, well or at least get the shop to do it hehe

OK yeah I can confirm the it was the PAC Steerwing wheel interface. Had the shop unplug it real quick and it has worked fine for days now.

what was the solution to this problem? Im having the same exact problem.

i would try programming something different to that button and see if the new button goes crazy, if so i would skip the SOURCE button in the PAC programming so at least every other button works

My F90BT is changing sources automatically too, and I also have a PAC installed.

Anyone find any fix? I still want to retain my steering wheel controllers so the PAC is a must. I don't want to have to remove the entire thing.
