My Garmin 2730 StreetPilot is now just a little over a year old. About six months ago I bought Terrie a 2720 StreetPilot for her car. On mine, from time to time when I turn it on a window pops up telling me that I'm using an out dated map and that I can log onto Garmin and download a new map. By the way, I also just ordered a Garmin 60 Csx handheld (to use when we're on vacation and rent a motorcycle)
While at Frys Electronics the other day, I saw cd for US maps 2008 series and I bought it.......thinkin I could update both Garmin StreetPilots. Got it home and updated my 2730 just fine but couldn't get it to download to the 2720. Said it was already assigned to another unit. After contacting Garmin, I learned that a map update is only good for one GPS and that you have to get a new update (if you want them current) for each, seperately.
I replied to them, suggesting that they make the unlock codes for up to three Garmin GPS units (much like the Norton Internet Security) and then the consumer would have more incentative to buy more than one GPS......maybe even one for each vehicle. The response that I got was that they'd not thought of that and will look into it. Of course, that will take some negotiation with the mapping company so it's not like it would happen tomorrow......but a good possability for down the road.
