Is bluetooth the only way to download a Navigator? It looks like it has some kind of port where the strip goes in. If we can't get built-in bluetooth to work, is there any reason to think that we can get a USB bluetooth adaptor to work, or will we be wasting our money? We are using a Windows simulator and I know the drivers are an issue. We've tried a lot of different stuff that hasn't worked, but I keep thinking there must be a way... I'm hoping that if we get a USB adaptor and use the drivers that go with it, that it might work, but I'm somewhat doubtful about the whole thing. We're using a PC laptop, but have Linux on it, using Wine to run CoPilot.
