Just Up graded from F900BT working just fine to a F90BT so I can put F900BT in my wifes car (Joan) After the install of the F90BT The map screen shows me to be 746 miles away in L.A. I am in Tucson ? Checked Navi settings it shows no GPS signal. Tried a reset three times. Then I Changed the antenna (Just in case) still no signal. I thing the unit is bad. I am going to exchange it. Unless somebody has a fix ? Put my old F900BT back in and it works just fine, so it's not a wire or installation problem. Thanks Jeff R.

sounds like a bad system to me, are you sure you let it set long enough to relocate itself (shouldn't be more that a few mins)

Thanks for the reply.

I drove my truck for 30 Minutes. No luck, odd that it didn't start but still no GPS signal recived. So it's DOA back to Pioneer.
