I like my V1 because it has directional arrows. It's never let me down in the 8 years I've owned it. I've only used it in HK for about 6 months though. Decided to take it out of my car in the US, and bring it back here after I got busted going at what i thought was a perfectly safe speed on the Easter Kowloon Corridor
. Damn undercover 535i wagons!
