Go live 1535
When I go onto mydrive connect I get unknown navcore version
The system software on your device is not known by the current environment. Please make sure to install compatible version.

Anyone seen this before I have windows 10 a tom tom go live 1535 talked to tech support no real help there? I cannot update the gps.

Thank you

Try a drum reset on the unit by holding the power button about 20 seconds till you hear the drum sounds. Also, are you using the cable that came with the device?

Further, try shutting down MDC and then do the drum reset on the device. Reopen MyDriveConnect and connect the device to the computer. Are you seeing the error now?
Using the cable that came with unit still have same problem tried on a couple of computers one on windows 7

Thank you

As promised I was following up on the case and I just got the response from the 2nd line team saying we should try the below troubleshooting, so kindly follow the below :

Factory reset

Soft reset

And then :

• Disconnect the device from the computer.

• Quit MyDrive Connect.

• Delete the HOME 3 folder manually. (default: C:\Users\username\AppData\Local\TomTom\HOME3)

• Restart MyDrive Connect.

• Connect the device to the computer.

• MyDrive Connect will then automatically process the jobs.

• After the jobs have been processed (and maybe during) the device will reboot.

• you should be able to update the device.
