Hi Treza, I used USB, 16GB, FAT32 formatted which the website said I need to have. It works now! Not sure what happened before, what I basically did was re-run the toolbox software again few times and finally got it to recognise the USB and produced the RLink2 serial ID which I used to register an account.
So for experiment, I did get an update and even downloaded app like calculator (didnt see any useful app at all apart from map updates that cost 150 - 350 dollars) and managed to install on the koleos.
Traffic update is still not available though and when I go to the RLink2 system info screen in the car, it still shows no signal and it didn't detect any IMEI. Did you have that issue before?
Thanks!
