Hi, I have a colorado 300 when I try to start it it shows just Garmin on the screen and gets stuck. It is impossible to switch off without removing batteries.
Problem first happened when unit was switched on an then ran out of batteries? (screen blank > changed batteries > stuck on switching on)
I read somewhere else, that this might be connected to a memory card which is too big. The unit worked fine with the 4GB card in for several weeks. Tried to remove the card but it doesn't make any difference.
Could it be that the internal memory is full (I recorded tracks for about one week)?
Quick help would be appreciated as I am currently travelling in India....
Thanks
B
