After reading the manual over and over, it finally clicked, you must leave the key on the accessories position and the radio switched on so thet "ERR" is displaying. Leave it on like this for an hour after which time it will reset back to "CODE" then enter your code again.
Remember with the code it is entered as follows:
Using the 1 2 3 4 memory keys with your code you MUST enter as follows, if code is 3241, this means
Hit the 1 Memory 3 times then a '3' will display
Hit the 2 Memory 2 times then a '2' will display
Hit the 3 Memory 4 times then a '4' will display
Hit the 4 Memory 1 time then a '1' will display
