can i install xm in my g35c i am prewired and if i can what exactly do i need and can i hide my antenna in the car or some where hidden ?

 

If you are pre-wired, then yes its an easy install. You need to get an XM receiver. You can mount the antenna either on the outside, or on the inside on the package shelf. Some say mounting on the inside hurts reception, but others report no problems with reception.
