Hi all, I just returned from the states with this great new combination speedo/tach. It was easy to install as I followed the instructions. Now that it is up and running I can't seem to change the colours or settings to suit my stlye. When you follow the instructions on how to access the main menu, all I get is the word DIAG. Would anybody have any thoughts on how to reset this gadget or what to do from here???? Any assistance is greatly appreciated.
