Garmin DEZL 770 does not show topo maps, any solution?

It's an automotive device to state the obvious. "Horses for courses" .. outdoor devices are for topo use.

Garmin DEZL 770 (HWID=2002) does not show any Unlocked Map.
You need a Firmware Patch, tomorrow morning I'll prepare for you an SD Package.
Stay tuned

**FireFox58** · 13th November 2018, 08:37 AM

These are custom SD flash kit only for:
1 - HWID 2002 devices (Dezl 770), firmware version 5.20
2 - HWID 2268 devices (Drive and DriveSmart 60-70), firmware version 5.70

Instructions:

Download the RAR file from the Link attached then extract directly to a clean microSD formatted in FAT32 (best using WinRar to extract).
If your device has a Firmware version lower than 5.20 (Dezl) or 5.70 (DriveSmart) all is okay, otherwise a firmware downgrade is advisable
You can download an older firmware release from here:

This downgarde may be not necessary, as i forced a firmware release higher in Packages (5.21 and 5.71)
Ensure the device is fully OFF (not in standby), insert the card in device and power on.
"Loader" will appear on screen for some time and the device will boot up when the flash of patched firmware is complete.
The device can reboot itsself during the process.
After the Patch is applied the device will be able to read Unlocked Maps.
When the flash has completed remove the card, in its root will be a new file named 154.bin.
That's a backup of the device's non-volatile memory region and may save your device at a later date.
You would be best to keep a copy of it somewhere safe for as long as you have the device.
In case of flashing of a new version of the Original Firmware the Patch must be repeated, so you have not run Garmin Express with device connected as the software update first Firmware Device if any available. Do one of the following alternative ways:
Methode 1 (with device NOT connected)
1. Get file GarminDevice.xml from your Device (you find it in folder \Garmin)
2. Put the file in a Removable device, as an SD Memory or an USB stick (8 or 16 GB) in folder \Garmin
3. Run Garmin Express, your Device will be recognized as well
4. Do all the Update you want (when GE ask you to reboot device, simply secure remove your memory from PC and reinsert again)
5. When Update finishes you will have ALL the files you need in the memory, simply move them into device.
6. Using this Tip you have all the vantages of Garmin Express, without any problem of bricking, and you leave the Firmware release untouched
Methode 2 (with device USB connected)
1. With the device connected GE copy new Firmware Update (if any available) into device and ask for reboot
2. Do not remove the device (this is very important) but move GUPDATE.GCD in your PC (you find it in folder \.System)
3. Patch your Firmware using Firmware Patcher. You get a file renamed as GUPDATE_Patched.GCD
  This file must be renamed as GUPDATE.GCD and copied onto device overwriting the existing one
4. Now you can surely reboot your device. The Firmware loaded will be patched as well

I remind to beware right HWID, your device could be hardbricked

For what it's worth I've never had an issue using US, EU & Aus Topo's in my progression of automotive Nuvi's 255, 50, 1390, 1450, 1490, 2597, 3597 & Street Pilot Android.

All Garmin devices, including automotives, are able to manage Topo Maps.
Obviously the Outdoor models have more features and take full advantages from the characteristics of these maps, but this does not mean that the Map is not displayed.
For example, I use TrekMap Italy v5 on my smartphone without any problem with Garmin Streetpilot Android

Fair go guys, i'm not a complete novice. I didn't say that it couldn't display a topo, it just won't work like in an outdoor device and if you use one for road or highway use it'll likely eventually route you incorrectly, even dangerously. I've had one try to send me the wrong way round a roundabout, or traffic circle you fellows might call them.

A word of warning about this firmware modding now. You may notice that the Universal Firmware Patcher thread is no longer visible here. There's a good reason for that so be very careful about openly offering modifications to allow the illegal use of unlocked maps. That's why i avoided addressing his problem directly. Blind Freddy would know that dezl 770 has protected firmware.

How is posting Universal Firmware Patcher violates Garmin copyright? The tool wasn't created by Garmin and if any copyright needed to be enforced it should be the creator of the tool, not Garmin.

@Butters
I did not mean to say that you are a "novice", if I gave this impression I apologize.
I simply wanted to say that the Topo Maps are displayed, even if with restrictions of functionality and use also on the automotive models.
As for the Warning on publishing Patch for the Firmware, I agree with the above statement from @osiris4isis: "why should not it be allowed?"
In any case, let us decide the MOD. If this is not allowed, just delete it

Tex: "How is posting Universal Firmware Patcher violates Garmin copyright?" Mate, you know i'm not a scaredy-cat usually right? But the answer to your question's pretty obvious surely? It breaches Garmin's EULA not to modify their device firmware and it's sole purpose is to allow use of illegally modified (unlocked) mapping on their protected devices.

@FireFox58
Sorry, i overreacted a bit there. But if you knew what i know you'd understand. Can't say more other than be warned that this behavior is being watched externally, that's what's being flagged by the thread disappearing. Don't forget the bitter lesson of last year please.
