My first SatNav, was an RAC instrument, which I didn't find to my satisfaction...

I've not used this for a number of years, but now want to pass it on to a friend to practice with, prior to them purchasing their own equipment...

I would like to delete all the information on that equipment, but cannot seem to find a means of doing so... Pressing the reset button has not achieved a pos result, unless there needs to be a combination of events, that will completely reset the equipment...

Any assistance will be appreciated...

Regards...

Robbie...
