Sorry mate, if you have a mk3 then you have v22 (3-1/63), v32 is for the other nav units and is the revision of the OS disc not the OS it holds.

As long as you followed the correct burn procedure then just bung it in.

Procedure:

Select the write speed as the slowest rated speed for the disc, you must do this and then burn on a good quality cd.

When its finished writing your new firmware cd,
Go to the car open the drivers door,
Go to the nav computer and press eject on drive,
Eject the map disc,
Switch ign to pos 1, leave door open.
Insert firmware disc into drive, follow instruction on nav screen.
Wait (approx 6 mins) till sat nav asks to eject cd and reboot.
Eject cd, and remove from drive
Confirm reboot.

That's it.

Do not switch off ignition or close the door when doing the upgrade.
