I settled on a used AIM MXL Pro05 dash with an appropriate sensor package. Part of the reason why is that many other drivers in the area with the same car use it, so there's a possibility of benchmarking myself against the front runners in the class
You need an external GPS device for Harry's to work properly. A lot of people who use their phones' GPS have problems. I have XGPS 160 paired with Harry's and it works like a charm.
