I had a Reich easydriver pro 1.8 fitted on my eriba when i bought it a few months ago, now trying to get the controls to work you press the red button and about every 10th or 20th time the light will do the usual flick round like it should on the controls but still doesn't sync. i've changed the battery on the controls but no better. any one else had anything like this? i chose that model because it was supposed to be the ideal model and to fit along side the spare wheel carrier. I've dropped it off this morning at the dealers where i bought it from.
