You are right, but in terms of price and stuff it's actually not bad. I need to buy a rugged tablet, all the ram mount stuff for it, external GPS receiver in many cases, get a premium account for Navi software to use offline maps... We already reached the price of the overlander...It looks like Jeffrey Dill and I were replying at the same time.
There is a trade-off get a device like this and hope the built in maps meet your needs. If they don't well it's a brick. Or use something on your phone or tablet with lots of different map layers. Yes, there is effort required to make sure you have maps downloaded but I find that a small price to pay for a lot of flexibility. Everyone has different needs. In my research this looks mostly like a much cheaper Garmin device with a few items added and a huge price increase. Not worth it.
But now I don't have the Garmin advantage of creating routes and planning stuff on my PC at home and I need to make sure I loaded the maps I need etc...
The overlander can still be pushed with more maps and usually the street navigation works better than any app available.
To me there's nothing comparable to the overlander at this time.
