I just got my Sirius Starmate Replay installed this weekend. I did not do it myself, since I am a total n00b. I had Circuit City do it and had the FM Module Relay installed with it too. I had to go back twice because they only did the hard wiring of the power the first time, the second was to install the FM Module Relay (which they should have done the first time). The FM Module Relay shuts off the FM antenna on the V so you don't get interference while using the FM transmitter in the Replay. I am happy with the install but and considering rewiring to one of the cubbies down the road. Right now it is windshield mounted in the left lower corner. I love my Sirius though! We have had it in the house for 9 months and I have been jonesing to get it in my V. I will post pics later!
