How To Reflash Navigation?

[lordviper]

Hi guys,
so over the weekend i updated the nav in my 2003 X5 to 32.2 everything is all good and it works great.

however, ive since discovered i can have a custom boot image!

so ive put that into the iso and have tried to reflash the 32.2 update with my custom one, but it wont work.
its almost as though the car thinks its up to date so wont apply my custom firmware, although on the screen it says everything has been update, i dont get the loading bar.

can anyone help me please?



thanks!
