Thread: GarminCure3 tool - the new way to create cure firmwares for Garmin devices

I've never encountered such weird behaviour....
Can you check if the PC detects any new devices when you connect your nuvi with ORIGINAL firmware (open device manager and then connect the cable)?
Is it possible that your cable is a Garmin Service USB cable?

No, my pc doesn�t detect anything, it�s like me connecting the bare cable... i�ve tried several cables with same result. i don�t what else to do...

Try this,this help me on problem like yours.

Flash with cure FW and then create backup of your nuvi (dont forget hiden folder .System)

Format nuvi to FAT32

Add back your backup and turn nuvi on

Go to hiden menu over cockpit and clear nonvol.

Can you also go to the battery menu (press and hold the battery icon until the menu appears) and tell us which captions change there when you connect the USB cable?

USB Device changes from no cable detected to Power Cable.
I limit USB changes from unknown to 1A
Power Source changes from Bat to Ext

Well, i�ve already tested with 4 different cables and in every port in my PC, with the same result. As said it works fine after cure FW but not after original FW is flashed.

Any help is trully apreciated.

thanks again.

well, followed instructions, still nothing... device not detected by PC.

weird huh

Then try using other cables and/or cleaning both USB connectors. If it still doesn't help then I can try to make a firmware patcher that forces entering the flash drive mode when a Power Cable is connected. However, this wouldn't be comfortable in everyday use.

Can you really do this? it�s worth to try.

You will have a problem using it with a Car Power supply if the sofware is patched to enter USB Mode with a Charger Cable.
