Although I have factory XM, I have used my MyFi in a rental car. The sound response is the worst using FM. You lose a lot of high end response. Although I haven't tried it, any kind of in line connection should be far superior to any wireless connection.Docmwj said:I have installed the Delphi MyFi in my RTL RL (blue).
Very easy, $10 per month if you commit long-term.
Currently using the FM transmitter with fair-good results. Wondering if it's worth the $100+ for the patch cord to the HU.
Really love the MyFi, listen to it at home, work and my RL.
Ebuyer.com has 'em for $209. Couldn't imagine purchasing a fixed unit when I can listen to satelite radio ANYWHERE....
