Actually, playing with it more it is really quick. The only thing is when you drag the map, it doesn't drag smoothly, it takes the whole screen with it and then redraws. It does it instantly though.
I've had some crashes, so I wouldn't say its usable..yet. This is the only thing keeping me from running Linux on my CarPC and its a pretty big disappointment to have to run Windows for that. If I can get this to work, I will be very, very happy.
Well, it works, but I would say barely. Although I almost wonder if they are iGuidance bugs causing the crash. When 2.1 comes out, I'll try it again. We could always put a bounty on iGuidance under Wine. The speed is definitely there.
I'm not even going to try to answer that. I tried normal wine, then I tried CodeWeavers, back to normal, somewhere in between it started working. If iGuidance worked better, I would be more concerned with being able to duplicate it. If I can get my hands on 2.1, I will see how that goes.
GPSDrive is very good. You can get voice with that too I believe using festival - not sure if its turn by turn voice nav or just information that gets spewed out. GPSDrive also supports storing waypoints in mySQL... you can wardrive with Kismet and do the same thing the netstumbler with mappoint does.
