Ok, so I have some information to add to this thread.....
One of the users on here had a dongle with the issue that many are describing. Plug it in, RED led is lit but no wifi or bluetooth.
So I bought it off him.........
I plugged it into my Volvo and it worked....straight away.....
It needed to be activated, so I had to find the wifi network on the screen and use passcode 12345678, and then the dongle activated. I then proceeded to update the firmware via 192.168.50.2.
So, I think the thing to take away from this is....for those of you with this issue, you really need to plug it into a supported vehicle to at least activate it (Volvo, Audi etc) as without activation, it appears that no bluetooth will be shown. Then update to the latest firmware. (As this is what may or may not contain fixes for your vehicle)
I now have 3 dongles, but only 2 cars

At least it makes testing new firmware safer

Also...I just plugged it into my Windows PC and it no longer shows as an Iphone. Just as an unidentified device.
So maybe the older firmware shows as an iPhone in Windows, but now it just shows as unidentified device, but it DOES work 100% in the Volvo....
