I picked this GPS mouse up on ebay a few months ago for $85... and it is worth every penny and then some!
First off, installation is a breeze.. plug it in, run the cd. Done.
I drove across country on my maiden Carputer trip and the GPS didn't slip up once.. I did have a few problems getting signal through my rear window, but once I ran the mouse out the window I got near perfect lock everytime and immediatly. It also has a magnetic base which just sticks right to the roof of the car. I drove through Arizona and Nevada heat and never had a single problem. I drove through 3 days of Rain up north... never a problem.
In fact, we just had 'a 1000 year storm here in NJ -- the kind of rain that comes once in a 1000 years ... 11" fell in a day. We're a federal disater area right now... and when I started Routis up during it.. the mouse worked perfectly... talk about waterproof!
I did have one problem recently where the reciever wouldn't get a lock. I changed USB ports and the problem disappeared. A sound problem I was having miraculously disappeared at the same time... weird.
I don't know why I'm posting this. I think I'm both tired, and surprised with the quality of this thing... maybe I'm looking for similar stories of it lasting or not lasting... maybe I just want to let everyone who's looking for a good usb gps reciever to go with the BU-303.
And no, I don't sell them. This isn't shameless advertising. Maybe people can point to this post when a newbie asks about GPS mice... lol
