Hey guys read a few things .

I purchased the 2014 disc burnt . Said it is the 4.C0 disc.

When I put it in all the screen does is reboot .

I'm being told I need to do the 4.31 firm ware update first ?

From what I've read this is correct !

Any advice thanks

Guys

 

I thought that was only for the 2005 Acura RL... In any case, the 4.31C disc contains the firmware update for the navigation drive in the trunk. Newer navigation update disc came with a separate disc to update the firmware and then install the new maps update(s). I still have a copy of the 4.31C disc if you're out of luck.

 

Thanks ! My RL is a 2005 .

I put the 4.C0 disc and it just reboots the acura navi screen.

Ok I will do the 4.31 firmware and see how that goes
