the magnetic XM antenna will work inside the car but works way better mounted on the outside. you want a clear shot at the sky for the best signal.
if you stop under a large over pass or just driving under one thats big enough, the signal cuts out, same goes for large trees in summer with full leaves. you can also lose signal when on mountain roads the mt can block it out sometimes.
but all that happens so rarely, its a non issue.
ill get a few close up for ya of the antenna wires. ive set up this way 6 times already on all my own 3 cars and trucks. plus 3 or 4 work trucks.
only 2 trucks ever got the full wire tuck detail, the rest were a bag of wires to set up if i used that truck that day. (i took it all out at the end of the day) i can rig XM into anything in less then 10 minutes, about how long it take to warm up a big truck. i even had a power port socket with jumpers on it to jump it into the fuse box of a truck if it had no power ports.
last place i worked the pick up i had to drive sometimes had no radio at all. so i took along a am/fm battery radio, and hooked xm up to that. im that good lol
Im ghetto fabulous lol
you can also buy a home kit, and take it off the cradle in the car, bring it inside and hook it up to your home stereo as well. after its wired up its as easy as putting it on the home cradle and its a go.
