I have an 07 Ram 1500 and it has the XM built into it. I was listening to XM the other day on my ride home from work and all of the sudded it just stopped and started flashing at channel 184. CD player, FM work on it perfect. But when I switch it over to XM, all it does is flash 184 really fast and wont play anything. Is it time to upgrade to an aftermarket or is there a fix for this? Thanks in advance!
