Just discovered, this plays XRCD also, not that there is much out in this format.
I have the XM receiver on order, and will try Joe Blacks excellent idea of putting both antennas in the rear wing. I don't want to put it under the dash for fear of losing signal strength, as it is now this can get a lockon inside a 5 story parking garage. I'd hate to lose any signal strength. My Garmin used to be fine...till it rained, in the rain GPS signal seems to lose strength. I have yet to raintest this, but I think its going to be hard to fool the combination of GPS and gyro sensor.
