Re: Corsa f sat nav update

Just apparently managed to update the Infotainment firmware and the maps, though the recommended PC application doesn't work for me. Just downloaded the two huge files and untared them onto a USB stick. Tar is about the oldest ever archive format and is without any compression. The untared files total almost exactly the size of the original .tar file. You don't use a compressed archive if the files you are archiving are already heavily compressed.
Installing the firmware update does give you reasonable feedback, including a creep bar. Installing the maps hides away. You _can_ get an indication that it's installing if you touch the i button to the left of the nav screen, but there's no progress indicator. And if you leave the USB stick in, it asks to install it again.
Now here's the problem. Since I installed the firmware update (before updating the maps) my satnav is showing a location approximately a quarter of a mile from where I'm parked, and that hasn't cleared up so far. I reckon the GPS circuitry probably needs resetting.
I found the "Expert Mode" screen, there's _always_ a hidden menu, but I don't have the PIN number which is annoying, It is _my_ car.
If all else fails I may try disconnecting the 12v battery, to force a reboot of the whole system.
