XM Radio, best set-up?

[cali yaris]

Audio is not my strength, I use a local shop for that. I'll ask them about the antennas that were used. I know they used double-sided tape to attach the antenna to the underside of the dash. Once, it fell off and reception went bye bye.

No loss of reception through underpasses, even works through Malibu Canyon (with one 10-second dropout), which is a very tight canyon I drive through regularly.

wow i cant beleave you dont lose reception under over passes like all other users do and even more with that in a bad spot . i tried on the dash in the center at the bottom of the front window in the middle of the defrosting vents and it sucked there and your is under the dash and has no problems tell me more i have a few different units in my car gps and satelite units . what antennas are you using ? i would like to hide my antenna if i dont lose reception but i dont think they go hand in hand please adise
