Guy on another forum has decided not to do the tablet thing and is selling his MX dongle. That's the one to get in my opinion. I think I remember him asking $50. If interested PM me for contact info. Only one wire really. Just need to hook the USB charger cord to a hot on ignition fuse if you want auto on and off. If you don't mind plugging and unplugging, and you are not going to stealth your cord, then you don't even have to do that. I did though!
