Saw your post about a mount for your GPS. Well, I'm new ot this too and just got an Explorist XL. Nice unit, nice features, ** L O U S Y ** customer support. But I digress...
About your mount. I did some looking around and came up with a mount by Lobster Mount. I received the thing last week and it is very well constructed. The suction mount works extemely well. It is a clever design to really keep the windshield mount in place. I gotta say that this is one nice mount. Also, while messing around with getting the right positioning on my windshield, I tightened the srews a bit too much and munged the arms that actually hold the GPS in place. I emailed the company and, within a day, had them thanking me for my purchase and sending me a complete set of new arms free of charge!! One short email to them mind you. No questions asked! Now THAT'S standing by your product.
I highly recommend Lobster Mounts.
