Hi guys,
I'm trying to install JCV.
I updated my nuvi 1300 to fw 5.20 using the webupdater, then I removed GUPDATE.gcd file (backup copy), I entered in diagnostic mode by pressing battery icon for 5 seconds and connected the USB cable to computer. But when I start updater.exe i find this error message :
The garmin device is not responding.please ensure the following and try again:
1.The garmin device's interface is set to Garmin or Host mode.
2.The cable is connected to the correct serial port.
3.The garmin device is turned on.
Any tips?
