dezlCam how to update maps without USB connection

Hi Everyone!

I'm facing a strange problem. I have a Garmin Dezlcam lmthd truck gps. I tried anything, but the PC won't recognise it. (Maybe usb port error). How I could make a map Sd card for the device?

Is it locked, or I am able to use the NTU 2024 map on an external SD card?

On the device back plate I see dezlcamLM It's a 6" truck GPS.

Type: Dezlcam
Hardware id: V6 SA3 16GB AUO CLXIN
Software version 3.50
GPS Firmware 3.05.20

Try reinstalling the Garmin USB drivers

You have Lifetime maps so this can be done. Check your PM

Yes it would need to be Patched to use Unlocked maps ,but you don't need to.

I have a Garmin DezlCam LMTHD that is not recognized by Garmin Express via USB and therefore I cannot update the maps. Is there a way to do this via an SD card?

Welcome to the forum.
It depends on what DezlCam you have but first install if you have not already.

Has this ever been visible on your PC ?

Yes, sir it is the LMTHD, It is not recognized by the Garmin Express. It recognized being plugged in to a USB port on the laptop, but Garmin Express does not see it.
I installed the driver and it made no difference.
I have owned this GPS since 10/9/2016. Bought from FactoryOutletsStore,com Worked good until summer 2024 when it failed to be recognized by the Garmin Express software. The symptom included Plugging the GPS into the Garmin USB cable into my HP laptop with Garmin Express. it would not recognize it so i could not update the software
Info from the GPS:
Model: dezlCam
Hardware version: V6 SA3 8GB AUO CLXIN
Software version: 3.80
Truck Services 27.20
I reinstalled Garmin Express and no change

Sounds like the garmindevice.xml might have got corrupted.
Plug in your device and go to the Garmin folder and make a copy of the garmindevice.xml and save it on your PC. Then go back to the Garmin folder and delete the garmindevice.xml unplug your device and turn off the device fully (hold the power button until it asks if you want to turn off the device).
Restart the device and plug back into your PC ,your device will create a new garmindevice.xml ,try Garmin Express again.
