Not sure why it complains about locked maps on boot-up if there's no maps loaded .... unless you have something on an inserted media card?

Now follow what i said in Post #407:
...... GE will see it and you can replace the detail maps. GE will also offer other software such as voices etc., look under Tools and Content>Utilities>Optional Updates. You'll need to add a [Only registered and activated users can see links. ] manually into its .System folder because Garmin doesn't update it, and the device can't work properly without one. ......
PS: Thanks for your kind comments, much appreciated. Also being in India you'd know first-hand how cyclones, monsoons and tropical lows/rain depressions cause havoc!
