For the past couple of weeks Ive been getting the "no signal" message from my XM. It is the factory installed unit that i have and yes my subscription is paid up! . Anyway i talked to the folks at XM to do all the resets and refreshes they can from their side but to no effect. The conclusion from one of their techs is that the receiver is malfunctioning. My question to you guys is do anyone know where the receiver is installed on out LS's and has anyone replaced the factory XM receiver before. Thanks in advance for all responses and advice.
