Okay here is the deal..I have a in dash panasonic sirius ready cd player in my car.I bought the vehicle used and the radio was in it when i got it. anyways I called panasonic they said i need a sirius receiver ( in know I dont need that becasue there is an option on the cd player that i turn on and it goes to the sirius radio screen) anyways then i call sirius and they say i need either a sid or a esn number which i have neither...I only have the model number and serial number...so if anyone could help me out that would be great. Thanks!
