Great! Is the update available via firmware update? If so can you send the procedure to download the file and install it in the Maestro unit? I can’t find my original paperwork.

Go to our website, login, and hook the maestro to the computer with the supplied USB cable. Hit the big green button that says "Flash your module". The website should walk you through the rest of the flashing procedure, and it will automatically give you the most up-to-date firmware.

Also having this issue. Tried viewing the images to check pinouts, but all the links are dead.

Have 2006 jetta TDI, pioneer avic-w8400nex, maestro rr. The obd2 connector is plugged into the vehicle obd2 port, feels a little loose, and radio is reporting obd2 error & not providing any gauge info.

If I knew which wires on the vehicle connector to splice into and which wire is which on the maestro connector, I'd hard wire it.

Please advise,
Thank you.

It's pins 6 and 14 at the OBD2. With the OBD adapter plugged in, you can trace the wires across the connector to the factory plug and that will show you where they need to connect to on the car.

Discovered that when checking other installs, brown red is can high, brown yellow can low. Tried obd2 pins connected directly to port in car, still not working.

Will be removing unit from car and reflashing again, this time while on call with tech support (they indicated failed status for flashing on their end, despite website reporting success on my end).

Thank you
