My vehicle is a 2003 Series II Disco TD5 manual. I am asking if anyone knows the procedure for entering the security code. I have the code. Tomorrow I intend disconnecting the battery so I will need to re-activate the radio. Unfortunately the radio instructions did not include a section on entering the code. The radio/CD player has 6 buttons on the front, a single CD slot at the top and vol/bass/reble control on left with band/menu/search on right. Beside the CD slot, on its left is the RDS and on its right is the traffic info button. It has no brand or model name however I have included a photo of the unit in the attachment
