I've had it for about three weeks...the source skips from my Ipod or from Sirius Sat.radio...Sirius also skips from one station to the next. I thought it was from bumps but it doesn't seem to correlate-sometimes it just jumps from Sirius to my Ipod. Any thoughts? I had it installed by a reputable dealer-just wondering if I should pull it and send it back or?? Thanks.
