LOCK 10 is an issue. You have 3 more attempts to unlock the system with the code. To do this you need to press and hold '6' whilst switching on the unit
1165 is the code you need. To enter the code, press 1 on your radio once, press 2, once, press 3, 6 times, press 4, 5 times then press number 5 to store the code.
You must see - - - - flashing before you enter the code. If the code does not unlock the unit you will have to have it reset manually.
