Thanks for your reply. I've had a readthru of your pointers.
I don't know how many that is acctually using OBDII. I think that the info I want (remaining distance on tank, average speed, average consumption, trip start time and duration, total trip distance...) is what people in general is after. What I'm saying is that something like that is not available at the moment (?) and that OBDII probably would be a lot more popular if there was.
If there was an application like that I would gladly pay upto say $40. I've spent a hundred on the OBDII interface already :-)
At the time this is of "nice to have" priority for me. I've got bigger hurdles to climb at the time :-)
Not knowing how far RR has gone since I last looked at it (flash an all), this is what I want if someone is in the business for this:
I would like it to work as a pop-up that stays up for maybe 60s and does not cover the full screen. It slides into screen and slides out. On it are fields for each data with explanation and a ticking clock.
