Re: RHB 430N Update to City Navigator NT 2016.10

As near as I can tell - this DOES NOT WORK for a newer (2015) 430N. I tried all the steps, but never could get the Garmin firmware to downgrade from 5.11. The radio downgraded - but not the Garmin firmware. If someone has successfully done this on a newer 430N - please - I'd love to be proved wrong.

The 2013+ 430N radios are different (unfortunately).
There were some 2011 radios that could not be updated at all...
Then there are some 2011-2012 radios that can be updated. Those radios the Garmin software updates to v3.

The 2013+ radios the Garmin software updates to v5.11.
My understanding is that the maps can be updated, but the maps must be added as 'supplemental' maps in the system.

I really wish I could help you but I've got a 2012 430N.
It's so frustrating that car manufacturers make it so difficult for consumers.

I work in the Information Technology field and years ago after seeing what the big names (Dell, HP, etc) do to lock you into their workstation platforms I stopped buying their desktops and I build my own so that I can easily upgrade when I want to.

This forum thread should be very helpful, but you need to start from the beginning and read all the information.

You can also search the Audio/Visual/Navigation sub-forum for everything about the 430N/RHB radio.

Updating the radio firmware is a separate task from updating the maps. You have to be on v33 (either of the v33 updates) to be able to update maps. The v50 update will not allow you to update maps.

Depending on how far you have updated your Garmin software...

The 2012 430N with less than v3 Garmin software you need to look for:
City Navigator North America NT 2014.40 ALL
And the related junction file:
D3060130A.JCV

If you have the v3 Garmin software then look for:
City Navigator North America NT 2016.20 ALL
And the junction file:
D3060190A.JCV

Create a Garmin folder and in that folder the gmapprom.img file (if the file is named gmapsupp.img just rename it with all lower case) and a JVC (folder) containing the JCV file.

As long as it uses the IMG file format, you should be good to go.

First you need to fine 33.02.01 and update to that with usb drive or cd. I used usb.
Find NT 2016.20 maps, do what everyone here is doing. Mousejet to unlock code needed to install maps.
Once maps are installed update to latest 50.xx.xx for the gray/black color scheme.

If you look hard enough you will find the files.
