I have the MiFi XM unit.
My model and others will transmit on various FM channels.
Mine transmits on 12 different FM frequencies.
Lower and upper FM frequencies.
88.1-88.9 and 106.7, 106.9 and 107.1-107-9.
Used to transmit to any FM speaker system in cars, home, portable radio, etc.
I placed my unit in the Tour-Pak. Out of sight and out of the weather.
Bought the PakPower Plug that fits 1997-2010 Tour-Paks from J&P.
Motorcycle Parts P Cycles
PN 382-834 ($34.99)
Just a few minutes to install but gives me a power outlet to plug my MyFi unit.
I have the magnetic antenna mounted under the fairing and ran the antenna lead back to the Tour-Pak.
Picked an unused FM channel that doesn't have any local channels on it.
I can listen to XM while traveling the US and nobody can see the unit.
Handy for stops so I don't have to worry about someone stealing my Satellite radio.
Doesn't get hit with rain or sun either.
A nice advantage to the FM transmissions is they do transmit for some distance.
Already tried it and found others that are riding with me can tune their radio to the same FM channel and hear what I hear.Of course, I get to chose the station.
Only "problem" is if I want to change the station, I have to do it while stopped.
Not a big problem for me as I generally keep it on the same station for long periods.
harley makes a great unit
They do make a nice unit but unfortunately it will stay with the bike for the next owner.
I like having my own unit and I can move it to the house or other vehicles and I retain ownership.
