Just looking for any pointers/advice from anyone who'se hooked these things up.I just received it a few days ago and if it ever stops snowing up here in VT I'm going to install it but any tips to make life easier would be appreciated.Specifically connecting to audio. Is there a direct FM input to the stock rover radio that I'm missingor do I have to settle with wireless/fm extender? And if so,seeing how there are two antennas on each side rear window does it matter what window theextender goes over? Thanks!
