I've already acquired a compatible Garmin GPS, and watching the prices for this as it has come down to $94 on amazon. My brother in law already got his for his car and he says it works pretty well...
Thanks for the tip about this on this forum...
EcoRoute HD, which is just a plug and play (onto the OBD port) and displays all sort of (real time) engine data AND can check OBD codes and reset them for $ 94 (if you already have a compatible Garmin GPS):
Jusr seeing the real time coolant temp. and ability to read and reset OBD SES codes is worth the $$, IMO. There are some cool fuel-efficiency calculators on this thing, too...
