I used a car kit and mounted it in front of the ignition key. Since the kit is not waterproof I just slipped it in a zip-lock bag and slid it on the mount. Worked perfectly until we cancelled our sattelite subscription.
I used an FM modulator, but a cassette adapter might be better to avoid interference.
Mounted my "car kit" sirius radio just in front of the ignition switch, plugged into a 12 volt outlet I wired into my left storage pocket and listen directly from the satellite radio via ear buds. I purchased an antenna with a really short lead which I velcroed in front of the radio. I purchased a more or less water tight cover for it. I purchased the antenna and cover from TSS radio.
Works great! Let us know what you do and how it works.
Not to worry about the "purchase" word! I really liked your answer and will likely use your ideas and rpeters549. I have the lifetime subscription and my wife has a very nice combo unit (AM, FM, CD, Sirius) in her car. Almost never listen to standard radio when in her car.
Where exactly is Coquitlam?
Have my Sirius mounted on a Ram mount using the car kit, on the left side handlebar. Running power, antenna and modulator wires up the handlebar inside the plastic sleeve.
Audio is fed to either the exterior or headset speakers, all of which are J&M. Sound is good, but would be better and louder if I could direct connect thru an audio in on the bike radio, which I don't have.
I use the SkyDock for the IPhone hooked to a cigarette lighter in my trunk. I plug in a 6' extender and run it up to the front of the bike. I placed a ram mount to the center below the key ignition and put the IPhone there. The SkyDock has its own fm transmitter but I also have a fm modulator (I think audiovox) installed on the bike as well. I purchased an antenna for motorcycles that is just behind the passengers backrest. I use it all the time and it works flawlessly.
I have an XM Onyx mounted to a Ram Mount. I drilled a hole in the ignition switch cover behind the key and mounted a Ram ball and an off-set ram ball there. I attached the GPS and XM radio so they sit on top of each other. Hooks into the bike audio via the tape deck as much better sound than the modulator. If I'm on the road, I either use my Nolan N-com or ear buds; in town I use the speakers.
I switch this back and forth between 3 bikes and my truck so I use a cigarette lighter power cable.
I'm still experimenting with shortening the antenna-about 2' seems to be the minimum for decent reception. Or you can coil the whole 23' around the ram mount.
I mounted my SkyFi docking station, FM wireless modulator, an additional power outlet in the "hump" of the travel trunk. I also have a place in there under the rear of the rack area for the antenna, I set the station before I get on as I know what I'm gonna listen to .... and it works without interfearance as the FM Modulator is not a foot from the radio antenna.
If I have something on the rack, then I have a hole I pass the antenna thought and simply stick it to the top of the rack or on top of whatever I have on the trunk.
It works so well on the 1500, that I removed my front handle bar mounted setup on the 1200 and remounted it the same, eliminated interfearance. I should add that in both cases, my docking station has a "button" made from aluminumback that is designed to fit a heavy dutyGE Communications mic clipand once snapped in place, no rotation happens. It means I can use these two setups interchangeably or in my older '77 Ford PU or .... any car if needed on a temp basis. My other vehicles have dedicated docking stations with wired modulators .... thanx Ebay.
Radio signals ...if you cut the distance between the transmitter (modulator) and reciever (antenna for AM / FM) by just half, you quadruple signal strength. I shortened it from several feet to under a foot.
Since I was using an FM modulator, I ran the antennae wires through the body and up on the factory radio antennae. Using the aux fuse block I wired a 12v lighter inlet and mounted it in the right glovebox as a power point. Ran the wires from there under the ignition plastic piece to plug in to the unit. Worked dandy (except for radio station interference if I got near Portland or some other towns).
