Does anyone know if there is a way to install Garmin topo software into the stock 2015 navigation system?
Not an owner of the Toyota Nav, but Map Databases and associated GUI software are generally vendor-specific (fairly vertical), and swapping amongst different brands/formats of Navigation MAP databases is a non-starter to my knowledge.
I'd love to get Garmin GPS GUI and Maps on my Alpine INA-W910, but it's simply not possible.
