I'm talking about devices that companies like TomTom or Garmin make. How do these things work? Do you have to pay for a subscription to the service or are map updates, etc. part of the purchase price? Also, to update I'm guessing you plug the device into the computer via a USB cable and then there is some sort of propierty software that syncs it,is this correct? I'm considering getting one, but I want to know all about them first.

There is no subscription fee for any of them that I know of. I think for some brands, the map updates cost money, but there is no monthly fee or anything similar.

And yes, that is commonly the method for update.

I could be wrong, but i think the TomTom uses Linux. :confused:

I have a Garmin StreetPilot c550. It works as a storage device, so to update you just download a file and put it in a folder on the thing. No need for any software.

There IS software to load other POI's, but I have that running through Wine problem-free.

Older Magellan units required a $100 fee to upgrade maps. But as prices drop, it makes more sense just to buy a new one than to upgrade the older technology.
