As I can read this forum you must be joking with us with all the new series of Garmin 2xx9. I'm still unable to install any new maps and now we are unable to install new FW. Great navigation. I can tell you guys, I have at home also Tomtom GO500 for more than half and I didn't have any single problem with it. In comparing to new Garmin I'm just pissed. And I'm not alone.
In case of need XML file, e-mail me.
