Read slowly, the following is the work of a confused mind.
The new tin top of Zil is one of these
It has a basic sort of single CD radio just now, but you can get an OEM looky likey SAT NAV setup for it which runs on Windows CE, much like this one.
Base on this being windows CE and having bluetooth, I'm thinkinng it might be possible to run one of the OBD readers on it along with an ELM327 based OBDII bluetooth deviced plugges into the diagnostics port.
There is software available which gives you access to the OS to run such software.
Thought anyone ?
