There are a couple of ways to go about it.
I do the BikeComm (
http://www.dmme.com.au/BikerCom.htm) at $750 you get 2 headsets PTT, music,GPS and UHF (handheld Icom/GME/Motorola) cables PLUS 2 extra BT connections (Phone and GPS). You want a different UHF - NO Problem I can make the cable
.
The Sena is very similar but limited in comparison, if you only want 1 headset it may be cheaper (the site linked is down at the mo)
ONE MAJOR THING TO REMEMBER if your on the bike everyday or 2nd charging a headset (and possibley a SR10 too
) will become very tedious, if your only on every 3 or 4 weeks you'll likely forget to and then wont have a working system SO wired is likely a better choice
If you are a one or 2 times a week or every weekend Wired OR Bluetooth (wireless) will be OK.
Personally I run the StarCom1 Digital, Uniden UH-015 (remote head car type UHF), TT Rider GPS (go Garmin if you can
), MP3 and 2 x (bike powered) StarCom Bluetooth modules, ALL Bike powered except the MP3, from the StarCom1 Duigital's switched outlet.
Digital direct to battery - plug in riders headset - everything lights up and I ride away (with a big smile on the dial
) only ever have to charge the MP3 about every 3 or 4 weeks.
The TT rider doesnt work all that well with a phone hence the2 x BTM, one does the GPS the other the phone.
If I had another hour I would go in depth with expalanations.
Maybe over the weekend
