If you check the computer for codes with a reader that reads abs... you might have better luck... unplug and replug your wheel speed sensors. Fronts plugs are on your upper control arms. Rear sensors are between the bed and frame just above the tires.
I am lifted and have issues with the front sensor wires being just a touch shorter than they should be.
I do have a scanner that does abs codes and it tells me which wheel has the issue. Might be worth a trip to autozone and have them scan... (engine light is not on with ABS code)
Google says that some of the JVC units have a master reset that will cause you to loose presets etc... If at that point it is still locked, you will probably have to call JVC.
model number of the head unit would probably help people answer your question.
I would like this as well.... I still like the factory bluetooth, but if you are on the phone and get in the truck there is a delay as the truck switches to bluetooth but the amp of the ogm1 is not on yet. Amp needs to come on as soon as the key is on.
