I have a 06 Expedition Limited with the Factory Nav Radio. My wife would like to have Bluetooth connectivity for her phone. I am thinking about replacing the Fac radio with an aftermarket Bluetooth Radio.

Questions -

Will the rear entertainment still play through the speakers?

Will the steering wheel controls still work with the new radio?

On the Fac radio there is an IR sensor at the top of the unit. Is this for the Automatic Climate control?

We use our phones or Garmin for navigation and really do not need a in-dash nav unit. Plus the current Nav CD's are out of date.

Thanks,
Jay
