Do you have to buy the XM radio from Honda for your xm ready installled radio can an mp3 player be attached to the Honda radio?
If it is xm ready radio, then all you have to do is pay the
monthly fee. You already have an xm radio and need nothing. Read
you owner's manual. If you buy the xm radio from the dealer it will
cost about $750.00 It is prewired for the 12 volt system of the
Honda. The roady 2 radio you buy at wall-mart or elsewhere is set
up with a 6 volt system. I bought my roady 2 at fry,s and fry,s
instlled it for around $80.00. did a very nice job on installing
it. The antenna was installed outside like roady suggested and hard
wired the radio to the frount lighter using the 6 volt adaptor that
the roady came with and wired it to the 12 volt system. Roady 2 has
a sell right now, that if you buy one Roady 2 one can send off for
a second one free.
