I have two cars that I own which have Carputers. (none have 9-pin RS-232 serial ports, btw -- all USB).
I would like to buy an XM receiver and be able to use it with the carputer in both cars. Can I use one receiver in both cars by switching them out? Or... can I buy 2 receivers and use only one subscription?
HARDWARE: Fujitsu Stylistic ST5111w/WiFi and dock, internal Hitachi 500G HD, external 1TB HD, Sierra Wireless Aircard 550, DVD-RW, BoomzBox HD radio, XM Commander, Delorme GPS, Saitek X-52 Pro joystick, BluSoleil Bluetooth, TPMS, FB, Elm327
I don't understand how this all works... let me make a list of the different components I've seen.
1) Mp3Car USB adapter for XM Direct
2) MJS-XMD2 XM MiniTuner USB PC Interface
3) XM Direct 2 CNP2000UC
4) XM Direct
How do all these component connect to each other and then to my PC (carputer) to be controlled by RoadRunner? Oh yes... I assume that somewhere in there is some kind of antennae that I would need in each car? What components are movable from one car to another? Lastly, can't the carputer just control one of those $30 XM units?
Sorry but this is all so cosmic for me and everything I read does nothing to connect the dots.
Part of the problem you're dealing with is that if you want something that's computer controllable, the options are very limited. Even that XM Direct unit still means you need 2 of Mitch's units plus 2 of the XM Direct units. The only savings is that you can get away with a single subscription. But it's going to cost you $340 in hardware (assuming you don't try to ebay the XM direct units). I would say the cheapest solution would be to buy a unit that has a car dock. Get a dock for each car. No PC control of it, but you'll save a ton of money.
