KO esprit II factory reset?

[tonydevon]

I bought one of these 2nd hand, to be honest I wish I had just waited and bought a 3vc as I can program these blindfold, but hey ho

its got models etc saved in the memory, what I really want to do is wipe the lot, full factory reset so that at least I know whats what

any hints on how to do it

soon as Im racing 2 cars I will get another set of radio, faffing about with trims looks like a pain LOL
