Will it be work on Nuvi 500?
The hardware of the zumo 220 and the nuvi 510 is the same. Don't try this if you have dissimilar hardware.
Also try at your own risk. There may be a way back using a "cure RGN".
This method is based on the "How to convert 3790us to 3790 Sg/My" thread on this forum. I am also using a patched RGN from firmware with 2 sections. Some words can be found there regarding "cure RGN"
What do you need?
1) Download N5xx firmware and Zumo firmware from for example [Only registered and activated users can see links. ]
[Only registered and activated users can see links. ]
How to use RGNTool? See the RGN tool website.
3) Garmin Updater.exe
See the "Garmin Updater.exe v.2.8.0" thread on this forum
A) RGN tool
Open Zumo firmware either in GCD (or RGN). At Overrides make sure none is
1. At fw_all.bin section, select Save. Zumo firmware fw_all.bin is saved at the
2. Open Nuvi firmware either in GCD (or RGN).
At fw_all.bin section, select Load and select Zumo fw_all.bin that has been
3.Take note of HWID for boot.bin (or select and copy). At this point HWID for
boot.bin (Nuvi HWID) is different from HWID for fw_all.bin (Zumo HWID).
4.At Overrides, tick HWID, and replace it with boot.bin HWID which is the original
firmware's HWID (= Nuvi value 723).
5. Finally save to RGN.
Reach preboot mode (for a Nuvi 510 this can be done by touching the battery icon until you enter a diagnostics screen)
tick USB mode ,drag&drop the .rgn in updater icon, flash your gps
You now have a Zumo/Nuvi hybrid and are now capable of e.g. disabling the annoying recalculation feature. It's annoying to bikers who need to follow a preloaded route...
Garmin still sees your gps as a Nuvi 510 and will try to install a recent Nuvi firmware.
You probably don't want that if you've gone to all this trouble...
Also move your maps to the .System folder and move the GPX, Text and Vehicle folders outside the Garmin folder and put them in the root of the Garmin drive letter using e.g. the explorer of your operating system.
I also had an annoying message at boot time:
" FM Traffic Provider database missing. Go to [Only registered and activated users can see links. ] to download it ."
Here's how to fix that:
put your GarminDevice.xml in a USB drive , Garmin folder, edit it in the first lines to prevent it download the sw update and run webupdater, it will detect your USBdrive as your nuvi and will download the traffic provider file in the pendrive.
After that, put the file in the right position on nuvi-
Probably it will create the right folder too in your USBdrive , or look at the GarminDevice.xml to find the right path
Many thx to catymag...

Cab the nuni be changed so it is recognized as a zumo 220, i read that some guy did it, bit don't know how ?
sounds cool, will try this tomorrow
hope I can get back to original fw if something goes wrong
will try to report results here
Finally! I knew I wasn't crazy to think this was possible. Do you have motorcycling mode on your hybrid? Do you have the gas gauge feature and the added functionality for extra data? Can you change the readouts of the lower left and right data points as with the zumo 220?
Sorry for all the questions but I was too cheap to buy the zumo 220 so I bought the Nuvi 500 when it was on sale for $150, then my nuvi was stolen so I found the zump 220 used for practically the same price. After all was said and done I found my Nuvi (it wasn't stolen, I was just a schmuck).
I lent the nuvi to a friend, looks like I'll have to get it back and try this myself.
