I've had a XL - 335 for a long time but never have trusted it as it never seemed to go the way I would go when I've tested it in our small town. Usually make printed maps with the computer ! Just recently went to a BIG city and ended up relying on the gps to find our hotel and again to get out of town and have become a believer. Until now it hasn't been much more than a dash ornament but after having it RESCUE us I've decided to learn about it's capabilities and what other options are available with these things. To that end and perhaps also to make some new friends I've joined this forum.
