I had the device the whole Kieler Woche 2011 in use and it works reliably in the maritime use, can be supplied with (own) map material, it can be read very well in sunlight and is really waterproof.
Great product, great service. Have directly after delivery the thing on a 4-day Kanutour used and it has me excellent services done. This combined with a top service from SVB (thanks to Mrs. Hentschel).
Very good GPS device with extensive features. The only drawback is the arrangement of the control buttons above the display, which one partially covers when operating. But you can live with it and even serve with one hand. I plugged in an 8GB Micro SD card and played many free cards. I also have all !! the POI offered by Garmin from their homepage loaded and on the mSD card in the directory (Must be created) GARMIN / POI via USB cable from the PC dubbed. After a restart you were immediately available. Conclusion: The purchase was worth it!
The device meets my expectations. Nevertheless, only 4 stars: I would like to use the device while cycling. It still lacks an adequate handlebar mount.
Display very good, settings very good, a detailed description unfortunately only in the Internet. Here you have to read, as many settings are possible. Sometimes a bit awkward. Conclusion: very good device, with a little practice also easy to use.
