Instead of paying so much for a Scanguage, I went with the portable solution. I bought the
ScanTool ODBLink WiFi and the DashCmd application for my iPhone. One advantage is that the hardware works on both my car and RV, while the software can maintain a profile for each vehicle.
I find it sufficient to use when I change driving profiles (e.g. starting up a mountain) to check MPG and driving style (fast freeway vs. country roads). I chose the WiFi to keep the Bluetooth available for my radio.
