Why don't USB car stereos offer an open source back up of settings!

I have to disconnect the battery on my truck to troubleshoot the old check engine light and traction control light (Most likely some sort of gas cap issue)

Anyway I have a kendwood KDC-BT752HD and I was annoyed that there isn't some way to back up a config file to a usb drive to save all my settings before I disconnect the battery...

It seems like a no brainer easy move for the car audio companies, especially as the radios become more complex and require extensive settings 12 levels deep...

 

Really how long does it take you to setup your HU? I can run through my settings in about 1 minute.
