ohoi

Same here - 2 works for me. I tested how long my 2700 NiMH batteries lasted: - 13 hours, the same as firmware 2.51. :-(

I've also had problems loading Topo Norwegian Topo Pro maps which I've reported earlier and now tested with firmware 2.4: The Topo Pro maps in Norway are divided and sold in 20 maps: Topo Pro cd 1 - Stavanger Topo Pro cd 2 - Kristiandsand - - Topo Pro cd 20 .... When I download 9 or more norwegian topo pro maps to my Colorado 300 (sd card) the GPS perfoms a auto shutoff when I select Map/Options/Select Map. (Sometimes also auto shutoff when I select map) Other experiance exact the same problem. For those who understand norwegian see: http://www.gps.no/mbbs2/forums/thread-view...004&posts=3 It seems to be a limit in numbers of maps that the GPS can handle. After what I can see this a serious matter in the firmware. I have used the latest firmware and different kinds of 2 gb SD cards. ( I've have also tried these sd cars and maps on my Nuvi 660 without problems! 9 Norwegian Topo Pro maps is less than 1gb.)

I loaded my Colorado 300 with a set of fresh alkaline Duracell Ultra m3 batteries, firmware 2.4. kl 15.00 I turned the gps on using no backlight. kl 19.00 the gps turned off, batteries low. Is this 15 houres?

Still, when I download 9 or more norwegian topo pro maps to my Colorado 300 (sd card) the GPS perfoms a auto shutoff when I select Map/Options/Select Map.

A few times when I have panned the map, suddenly the screen has gone black and the unit has turned off by itself. It is not the batteries. Is this a known issue??
