I thought they would be great as I have never had a garmin do that & liked the 5" screens on them.
Ill stick to my CO 300 & 295 units I guess.
I have seen the 50LM units do this. The unit needs to be off when you insert the card. When I did this, everything was fine. Also, if you ever have any nuvi lock up, simply hold down the power button for 10 seconds continously and it will reboot the unit. This tip will work for virtually all Nuvis and is the reason so many Garmins and actually all types of automotive units go back.
