Does anyone here use a cell phone GPS navigation system & weather radar in their MINI? (compatible that is). I was thinking about buying a GPS system but I like the radar satelite weather maps a cell phone offers. I was wondering just how reliable the weather radar (data plan) is. The GPS would just be an added benefit for me. But how reliable/good is the GPS system also? Especially when you are out of your local area? Or would you have to "plug" in your area first? Any suggestions? Not using a GPS (Garmin type) system, but just a cell phone. Yes, I have the bluetooth package & use it now with my Motorola Razer 3V. Oh, I have the 2007 Cooper S. NJP
