Never a big fan of Fm transmitter for connectivity, however the o7 V8V seems to be ideal for the placement of the device, as the lighter and antenna are in close proximity. TuneLink auto connects to iphone via bluetooth and can be paired simultaneously with the cars phone bluetooth and switches back and forth automatically! NO WIRES. It plugs into the lighter and thats it! There is an app for iphone and android and works pretty well. I have the premium sound in my o7 and I have only heard better systems in a handful of other cars that were much newer. The sound quality does not match a cd, but it is 95% there. In my case the diminished sound quality doesn't bother me because it is still far superior to most. A bonus is a charger that will charge not just a phone, but an IPAD! (remember a thread about that)
