710 shut down and start up problem with 9026

After my successful upgrade of my ageing 710 with 9026 (with all your excellent help) I have discovered a niggling problem. When it is connected to the mount and the power is on if you shut it down it won't fire up again without a reset. Turn the power off or dissconnect from the mount and it works fine do a reset and it will fire up on the mount, have tried clearflash but no different.
It is annoying because my car charger does not go off with the ignition

The Navcore is not meant for your device, so you can not expect it to fully support your dock.

Ah ok I will have to live with it then because I love the rest of the features, just thought I would ask as you lads seem to have a fix for most things lol,
