Good morning and a happy new year ( a better one at any rate! ) to all
sorry if this has been detailed somewhere else. I did ran a search but was unable to come up with quite what I need. So...
I need to know if I will lose car radio data or other data when I temporarily ( 3000 sec ) unplug the 12v battery to install the emobe LeafBox range extender
any workaround ?

so far I've found special devices that plug into the obd2 and are powered through the 12v cigarette lighter socket or the mains
obd2 data save devices
