Ohhh SNAP!
I got it working
how, you might ask? well, me am GENIUS
i noticed on the mapquest d/l page they have different versions. I also notice that on the page listing the available devices, they tell you which ones need an external GPS.
Well, the Tilt does not require an external GPS.
They also have a separate CAB for the tilt.
so, what the hell, download and install the tilt cab. it takes and fires up.
go to GPS, nothing.
so, i use the Holux GPS viewer program to start the gps manually.
then, i restart mapquest and BAM i got a fix!

this is where you get the cabs. however, you need a valid activation code to get it working.
you should still be able to sign up for the trial.
DO IT NOW, I COMMAND YOU!
UPDATE: I just set up the AstroGPSLauncher with this program, and it works!
