Preemptive apology if this is the wrong section in the forum.

I would like to automatically update my "WinCE" radio via the SD card using the "Toolbox" from naviextras.com, but every time I try, I get the message: "Connect your navigation device to your brand new car and switch the ignition on." However, when I connect it, nothing happens. Any ideas? I also don't know the brand of the radio because it's not listed anywhere.
