Re: Garmin updates
As far as I know, updates need to be purchased through Garmin who will supply you with an unlock code that is specific to your device. If you don't get this unlock code, you won't be able to use the updated maps on your device. Garmin used to allow customers to get an additional (total of two) unlock codes for instances where you had more than one device in the family, but this practice was abused, and so they've stopped doing it. Now, you can only get one unlock code per pruchase, but they've brought the price down a more reasonable level of around $70, versus the old prices of about $150
I wish I could think of clever things to say in my signature.
