I've finally removed the V26.09A patch from my system, but the changes have already been made; the NAV is now in European/GB mode instead of USA.
I have now installed V26 with a modified splash screen. However, I am scheduled to bring my car into the dealer on Friday for them to recode my nav (for free) back to the US mode. Before I do that, should I reinstall V26 with the OEM splash screen?
Also, if I do go back to the OEM screen and they recode the system. Can I reinstall the V26 OS with my modified splash screen and still have the system remain in USA mode? I downloaded the V26 OS from this forum.
Sorry for the n00b questions. Thanks in advance for your replies.
