Is there an app that can read the Garmin maps files and use them with the built-in GPS? I have the Wi-Fi only Flyer and I'm going to Europe for a few months. I have the European maps back because I bought it on MircoSD in 2010 when I spent a few months in Europe -- I'd just much rather use it on my Flyer than have to carry around the Garmin GPS . . . .
