Well, I think the title starts off my intentions fairly well.

I have a 04 TL.
I have never upgraded the Navi.

I think I'm going to treat myself and order the new 3.6 navi disk.

However, it would appear that some other advances have been made with regards to changing the bootup logo, disclaimer text and getting rid of having to press the OK button.

I'd be willing to pay a small amount of money to somebody who would help me perform these customizations on my navi system.

Please PM me if you are interested.

Thanks.
Nic.
