Ok Unit

Yeah battery life sucks on this thing but if you use it for your vehicle then a power adapter overcomes this. Have a hard time getting satellites at night... Don't understand that one. Getting an external antenna for it since I use it in the vehicle primarily. Got mine for $50 from a pawn shop so not too big of a deal there. Setting up single point navigation on it is kinda cumbersome especially if you're looking to navigate to 1 way point without setting up a route. Having the Highway maps on it and the ability to expand on that with the upgrade kit (If I can ever find it) really does make it worth what I paid for it.
