I suspected as much, just wanted to be sure. Couple of months ago I was getting ready for my Australia trip and my GPS would constantly reboot in testing with IMG made from Map Source Data. You were kind enough to provide untouched IMG and my Garmin performed flawlessly with it for entire month I was there. Can't thank you enough for that.
Since I'm heading for Europe in two months I just want to avoid same issues. I'll wait till map gets officially released and someone, hopefully, posts original locked IMG (and ASR/SRX files).
