Ok, moments after answering my own last post by searching, I searched for this question and found it was an unasked topic!

Is there a chance in hell to add a factory nav system to an 06 HAH? The dash spot looks the same with a different facade for the non nav radio so the hole is there.

Can't imagine it would be a piece of cake but it's a nice system and the car I'm looking at is void of it of course.

 

If you search on vtec.net and driveaccord.net, you will find people that have done it and even done a write up. From what I have read of their experience it is doable, but not for the faint of heart. Finding all parts can be difficult/expensive. You are better off either adding a portable GPS (Garmin and pthers) or install a double-DIN radio with nav in the cubby below factory radio.

 

Thanks, much more rational approaches...
