Minimum 2G version for AMI External device install

[Dubbs]

Hi all,

I have ordered the 2G External device AMI 4E0057785F and 30pin iPod cable

My current MMI version is 28.6.0 0620

HW 6300D2

Could anyone advise if I need to do an MMI upgrade first and if so?

1. Which version do I need to have installed
2. What is the upgrade path to that version (i.e, is there a stepped upgrade path or do I just go straight to that version)
3. Is there any benefit in going higher than the stated minimum version and if so best way to do so (again in steps or just from my version to latest)
4. best place to get FW upgrades from and I assume I need to burn these to a particular type of DVD? If so which?

I'll go take a look for firmware upgrade FAQ/Stickies as well now....

Thanks in advance to anyone that can help me
