I've kind of changed my mind, for the time being. For now I'm going to return this part and just buy a Garmin. With the iPhone 5 launching in a few weeks, trying to pay off this car, and wanting to buy a new bike...I'd rather conserve the funds until I'm sure of what I can do.
Don't get me wrong, I still plan on replacing this idiotic non-Nav system with the full Nav edition, but from this point forward I'm going to make sure of what I'm doing before spending the cash. Hopefully Ford will soon take their heads out of whatever places they're currently in and starts offering an upgrade solution.
