A:AnswerThis unit comes with a corded antenna that mounts on the roof of the vehicle. I placed ours on the dash and routed the cable out-of-sight and it works fine. Highly recommended.
A:AnswerThere are three connect options to your car sound system with this tuner. It does not use the display on your car radio.
1) Bluetooth which is wireless.
2) Aux connector on your car stereo. A cable is included.
3) FM broadcast. Your radio would need to be working.
A:AnswerIt is pretty easy to install yourself. Everything you need is in the box. In the first call I installed XM, I put the antenna on the dash near the windshield and it worked fine.
A:AnswerThe antenna is supplied and has a magnetic base, so you can move it from one vehicle to the next (or boat). Only caveat is that you generally will be running the wire in moulding etc. on the vehicle, so disrupting your clean wiring setup each time might be a hassle. Might be worth looking online for a second antenna if you want "plug and play" approach.
