Ok, so be patient with it - sometimes it will do this for a while but should settle down - the important thing is that you've got an alternative to a Hard Disk, so the system will carry on working (apart from the odd restarts). Mine did this a few times and then hasn't done it for 8 months now.

If you cloned the hard drive and copied it back, this could be one reason, but you can always reload the firmware on USB and reset the system, which will reload the firmware and overwrite the old installation and partitions for you. That may be a solution if you are getting frequent restarts. If doing this, you will need to reload your maps on again though.

Ok i did another firmware install.
A few weeks in now and still frequent resets unfortunately.
I didnt need to reinstall the maps though so perhaps i did something wrong?
After install do i need to reset to factory settings?

If you reset to factory settings it just sets everything back to defaults - so you will lose radio stations programming, the loudness and equaliser settings, phone pairing, recent journeys and phone calls etc and possible any jukebox files you may have created.

In my previous post, I wasn't very clear, but what I meant to say was that if you previously cloned the hard drive which already has some hard drive errors, you may have cloned any corrupt files errors over to the new SD card - especially if you did a raw or sector by sector copy.

In my guide, this project was originally intended as a backup or an alternative to continuing to use the Hard Drive - because if the Hard Drive fails at some point in the future, getting a compatible automotive grade replacement is almost impossible. My Hard Drive was perfect, and I wanted to preserve it. So I originally cloned it, but in the end just formatted the CF Card and reinstalled the operating system which created the new partitions from the firmware.

So you have nothing to loose at this stage by formatting the CF card with FAT32, put it back in the NG4 and boot with the USB on the firmware. Keep the engine running all the time. Leave the maps for a while and just use the unit as it for a few days, then if you are happy, reinstall your maps.

Just make sure you don't use a UDMA 7 CF card - stick to UDMA 6.
