I had actually thought it as Ersatzgerat for hiking car rides and boat trips. Garmin should consider its policy cards. Soon no one will buy !!!. Otherwise, I'm with my montana 600 satisfied. Small Tits described as in other reviews included here also. BlueChart is empfehleneswert- connecting water and land linkable. Unfortunately, not in shared maps. What I particularly Bemängele- Garmin memory card usage. I can not connect micro SD card with other card materials. Eg 8GB Memory Card Topo Germany it CityNavigator plan additionally save Gpx points. The non ?????? possible at a sauteuren Navi. A little Verarschung by Garmin is available. eg Support Request Why can not these cards are kopert on a memory card (even allowed in MS). Who's licensors. How Can I Save the extra Gpx points. (SD card) Answer licensing reasons? Where? You can not combine data. GPX data only in Greätspeicher available. I mean verarschung. Because 1 backup must always be possible !!!. Thank Garmin. Service very good exchange Leisure and AutoNavi tip. much better than Falk Ibex 30 Cross. Boat Cards perfect !! - sauteuer !!!! card details !!!. a little coarser than the Falk. GPS search on power press Zack has arrived very quickly. When Falk unfortunately dauert`s very long. !!!!!. If you do not look necessarily on very detailed accurate maps can be very satisfied with this device. But Falk has finished Ilgen auere cards !!! AutoNavi is in which a closer and a little better, despite long Gps search. !!!! Without AutoNavi (top maps). Falk premium card Germany 3.2 top goes but without AutoNavi. Falk Can not boot !!!!
