Why All the Hate on these things? It has been 1 of the best money well spent for me. Used Velcro to stick it to the dash mate in the middle. Not hard at all to read. Awesome little gadget. Yes the usb acts as a passthrough, so you can run other software on a laptop, but why? You have all of the info right in your face, No connecting and disconnecting and waiting for a pc to boot, cluttering valuable space, etc etc. Its Simple, Informative, and could save u $$$.

No I have no association with these guys!
