PV1 said:How are you closing CaniOn? Do you press the back button, then say yes to close CaniOn, or do you just hit the Home button?
Maybe try to open CaniOn, make your setting changes, then press the back button and exit CaniOn. Do this away from the car so that the OBDLink doesn't connect. Then re-open it and see if the settings stick.
Holy cow! Thanks, PV1! That was it. I had been just letting the "auto close" app I have running in the background shut everything down when power is disconnected from the tablet (e.g. ignition key turned off). I have my tablet up in my work office right now charging. I tried doing what you suggested; making my changes, tapping the back button, and selecting yes when Canion asks if I really want to close the program. When I reopened Canion, all my custom settings were intact. Thanks again. That was REALLY bugging the heck out of me!
