Ok now i seem to have a different set of problems LOL. All cables connected correctly.
power everything up (all batteries have a good charge).....green light on ECU flickers and red light on data terminal flickers...No display on data terminal at all[

Update: Loss of power and D/T display seems to be intermittent. Now all up and running fine but still wont recognise the learn radio procedure. There should be a smiley for pulling hair out
