but I thought one of the coolest feature of GPSapp was that it shows your MPH... maybe something simple could be written to grab the mph info from the gps to throw a flag when you go below 30?

Although something like this would be theoretically possible, I'd prefer to have this be separate from the empeg. There are times when I drive without the empeg, or when I've got it turned off, and I don't want to depend upon it in order to have my radar detector work properly.

Besides, there's still some bugs in GPSapp (or maybe they're hijack bugs) that cause the I/O to lock up after you've left it running a while. I'd rather have something more reliable than that controlling my radar detector.
