does it have a serial port? I've recently fitted a meajolt to my escort and had massive problems getting my laptop to talk to it via serial/usb adaptor. The cheap ebay adaptors arent worth the money. In the end i had to use an expensive one from triggerwheels and use an older laptop running windows 2000/xp. I know its slightly different but it caused me big hasstle for weeks!.......in my opinion if you do use an adaptor buy a good quality one.
hope this helps
