Beware this function

I received my Garmin 2445LMT last night. After connecting it to my PC I ran the Express updater system. After several goes I managed to update the system, but when trying to update the maps, firstly the express system reloaded with a tick in the box near the bottom and promptly unloaded itself. After reloading I tried to update the western europe maps only to be told there wasnt enough room and to insert a Micro SD card (not supplied). I tried several more times and thought I was successfull but found that I now only had Spain and Portugal maps installed. I gave up after this and returned the unit. I think I will go for a Tom Tom
