mkIII nav v27
 

i bought a v27 nav disk for my 525 e39 from ebay it updates fine but at the end does not tell me whats version has been installed i.e i think it should be 7. i download v27 from this site with the x5 splash screen(nice) but it does not update the screen goes blank and the disk gets stuck i tried it with many disks but they all did the same thing. if v27 is ony for the mk4 nav what is the latest ver for mkIII and where can i get it please. thanks in advance lee in london england!!!!!!

(just a little thing the mk4 units on ebay are going for £400 to £500 but i phoned my bmw stealership today to check out the price and the guy told me they are £365 so was he wrong or are people on ebay buying them and putting on £100 if i get one from bmw i will let you know what i paid if they are £365 i will be defo getting one!!!!)

MK III Nav v27 upgrade success
 

I am a complete newbie to BMW. Bought on the spur of the moment a 2001 BMW 540iA from CarMax. It has NAV, DSP, no CD changer, 16:9 screen. 46K miles. Had 3-20 Nav software. Found v.27 software, found CD-key for MK-III. Update went smoothly, yes it asked for the CD key disk. I had made one. Plugged an address in and went for a ride and it took me there without problem. You guys are the bomb. That's good.

can you tell me where did you get the cd key for the upgrade, Im trying to upgrade mine too
