Hi Jackay,

I also have an Australian X5 (2004 3.0d) and have recently upgraded to v25 without any problems, others have too. I haven't yet tried the downgrade upgrade trick to et rid of accept but again other Australian vehicle owners have.

Also regarding homelink - I ended up replacing the insides of the homelink control with the insides of one of my handheld remotes and it works perfectly and has the buttons illuminated and powered from the car. While its not ideal I found that was the only way to get it working with my gates which are ATA. Let me know if you want more information.

cheers,
Seedar.
