Radio code!!

Hi folks. So my td5 has just had a new engine fitted, the radio now wants a code. After looking in my manual the radio code is written in the front (7051) but there is no number 7 Radio button only upto 6. Any ideas would be appreciated!

From RAVE:

Switch on the radio (‘CODE’ appears in the display). Press pre-set button 1.
Press either the up or down tuning button until the first digit of the security code appears in the display. Press pre-set 1 to store the first digit in the unit's
memory.
Use either tuning button to select the second digit of the code (until the correct digit appears in the display). Press pre-set 1 to store the second digit.
Select the third digit, again using the tuning buttons (until the correct digit is displayed). Press pre-set 1 to store the third digit.
Select the final digit (the display now shows the full four digit code). Press pre-set 1 to store the final digit.

If an incorrect code has been entered, the first time delay period commences. During the delay period, ‘Err’, ‘CODE WAIT’ or ‘WAIT’ appears in the display - DO NOT switch off. At the end of the delay period, ‘CODE’ reappears in the display and you can then enter the correct code. Remember; the time delay period doubles each time an incorrect code is entered.

Thank you!! Will try this in the morning!
