Firmware/software upgrade for North American Acura/Honda running ver 4.x navi
I ran into a weird situation with 2005 Acura RL (it is build with ver 4.x nav system, the one that works on White/Grey nav disks).
It has an original disk release 4.31 and it's program database version 1.10.0000. I tried to load the disk of release 4.B1 but it can't read it. The splash screen keeps rebooting.
When I put the old disk to the DVD drive the system boots and shows maps. The same disk works nicely on Honda Odyssey 2008. The only thought that comes to my mind is that the intermediate firmware/software upgrade is required. Any ideas where to get it?
Editing my post. I figured that I need this CD ""honda/acura navigation update setup disc for 05/06 models". Any idea where to get it ? Has anyone come across it ?
