I bought a new Mercury Mariner Hybrid. On the window sticker it said standard equipment - Radio Satellite Ready - Plays MP3's. Guess what, if you have the UPGRADED Radio/NAV system ($3700. Plus) It is NOT SATELLITE capable, nor will it play MP3 files. FORDS solution is an aftermarket velcro it to the dash Satellite radio from Best Buy. What a crock...This also applies to the Ford Escape. The dealer even looked it up and said it is Satellite capable....Beware if you want Satellite. Also, the navigation system is very awkward and difficult to use, unlike the system in say their Mountaineer which is great. FORD BLEW IT ON THIS.
