how to upgrade the NAV600 to a NAV900.

[dcarrolluk]

This upgrade will not enable bluetooth or anything else you don't already have to start with it only activates 3d maps
so whoever told you that did not have a clue what they were talking about
it will also not do anything to your vehicle settings so what settings do you think you are missing ???
and what bluetooth problems were you having prior to doing the nav600/900 upgrade.

I had the phone buttons on my wheel but no "phone" menu in the config, I did not realise this meant that it hadnt been activated, I asked a friend who has the same car and he said upgrade to a navi 900 and it should work. So I did.

No The only config I get in "vehicle settings" is chime alerts. no comfort settings or anything.
