Hi Andy,

I hope you don't mind me reaching out here.

Thanks to your PDF, I installed the CHSTEK 7862 head unit in my Boxster S. I want to do a full back-up of all settings and files but am getting an error message. You will see from the linked photos the error message I got when I followed the instructions on p.53 of the PDF. The other two photos show the installed software & firmware. Do you know the fix? Thank you in advance.

Here are direct links to the photos on my dropbox:
