Is there a product (Garmin preferred) that has the following:
1) Portable w/internal power supply
2) External antena and AC power supply
3) Base map for Auto use that is up-to-date that covers the entire US with the ability to store locations, previous routes etc. Also, very user friendly attributes for auto use (voice, arrows, easy inputs etc.)
4) The ability to create routes on a pc and upload the file to the unit (does this require additional software not supplied with the unit?)
5) expandable memory, preferrably generic card types (CF/SD etc.)
6) Topographical and water maps
7) And last but not least, the ability to have at my disposal an auto route to the woods, topo maps through the trails in a state park, and then out of the car to the boat and then around the lake.
Is there such a product that allows seamless or somewhere close to seamless access to multiple map types (topo, auto, water)? Are the Garmin memory cards proprietary and if so, will they allow you to add additional map detail? I guess at the end of the day, I want the unit for 90% car use without needing to upload any maps....then I want to be able to add topo and water maps on a memory card for other uses.
Thanks in advance.
