I have a 06 F 150 with a factory sound system that has serius satalite radio. I bout this truck used, so I don't have the ESN # to check into my serius account. Is there any way to get that from the system?

 

Yes. I can't remember what it is though. I beleive you have to be in the aux mode (sat) and then hold the 1 button until it pops up. Either way, call Sirius and they SHOULD be able to tell you after you tell them what your vehicle is(that is how I've done it in the past) if they can't ask to speak to someone else.....
