Ive posted this once already in 2 threads here because I wasnt sure which one it was more appropriate for but aparently IM NOT ALLOWED TO so they were both deleted! just gave me a bad taste about this site feel that it was completely uncalled for to remove them both could have left one post.

I have a 2005 Accord with the factory navi I know there is a mod out there to change the backround at the start up screen, I lost the link I had to it a while ago so if anyone could help me out here I would appreciate it!

 

I've been doing this on my 2004 Accord for w long while. Here is the information you seek:

The instructions there worked great for me too.

AND, if you go to this site:

you can find the Nag hack bypass so you don't have to click OK.

Acura, which uses the same navigation DVD, has posted some version specific hacks at:
