OnStar Remotelink standby time

[morrislee]

I have got my 4G upgrade from the dealership, as far as I know, the new hardware will allow me to use remotelink for up to 10 days when I leave the truck unattended.

 

Is there any way to make this longer? I have dual battery so I would expect pushing it to 20 days is not a big deal, maybe a relay between a fuse to automatically restart onstar module day counter?

 

Any pointer to where to start trying would be great or if anyone has done this already
