Got xM installed in my box today and while heading home I drove over some railroad tracks (cant avoid them). Now its flashing antenna on the screen instead of the channel. According to the book I need to check the connections.. the on on top of the car seems alright...


Long story short should I just take the car back and have the dealer rework it? Anyway they can instal it a little more sturdier.

 

first return the unit and buy Sirius. J/K. well sorta.

anyway, if you know where the tuner box is check it to make sure the antenna connection is ok. probably what happened is the antenna end came out when you hit the railroad tracks.
if then end is securely in the tuner box and you still get the antenna error, you will have to make sure there is no kinks in the antenna cable.
my guess is that the cable came out of the turner box.
