Contemplating a head upgrade on my 2000 UZJ100. Figure as long as I'm upgrading I'd also like to pick up the ability to navigate off road. So I'm leaning toward one of the Kenwood/Garmin units.
Question: Is there any known way to make sure the device will drive a 24k Topo? Is it just a matter of if it has a SD slot it will work? What about units like the 6180 that use DVD/USB to update maps? From what I've read it's just a matter of navigating to the map menu and pointing it to the SD card. However, there's been other posts that indicate that the units with the more advanced graphics (such as lane indicators) don't play well with flat Topos.
Right now I'm looking at the 5160, 6180, or 6980.
