I to have lost everything with the OGM-1 except the fasten seat belt chime. I have NO Low Fuel, lights on, key in ignition or, door ajar chimes at all. The turn signels are also at a very low volume. I undrestand that the chimes don't work when the radio if off but the the door ajar and key in ignition chimes should work when the truck is running and I open the door. I would be nice if advent would look into this and let us know if it is something they can fix or not. This is also very important in my opinion too.
