Garmin seems to be the 800# gorilla in the waterproof-for-motorcycle GPS game; Tom Tom is a little cheaper and DeLorme even cheaper still. Found on Ebay direct imports from China for $150 - $175 (US) with 4.3" touch screen, operating system is Win CE 6.0, bunches of bells and whistles best I can tell. And the vendors explain Garmin's high pricing as "name recognition" which is not all that far off base. Question is: anyone have any experience with these units? The sellers all have high seller rankings but they're clear as mud about software sources. Most state "This model is compatible with most brands of GPS software - however hardware specific software such as Garmin may not run on this unit". I know that Garmin produces their own software and others just use a Windows-based software. Anyone with any experience with these units? To view just goto Ebay and search "motorcycle gps" and you'll get thousands of hits and dozens of these <$200 units; some are "Rage" and others are "Peaklife".
