HUD question for GLC
I have a quick question regarding the GLC I have purchased recently in Australia.
The car is fitted with Head Up Display (HUD) function. I think HUD is linked to the default navigation system named Garmin which means it projects the by turn directions from Garmin (installed in the provided SD card) to the screen via HUD.
One question I have: is it possible to use an alternative navigation system, maybe via SD card (where Garmin is installed) or USB, and project that to HUD? I appreciate that I can use Apple Carplay to project Apple maps to the central screen (but unable to project this to HUD). However I am keen to use, for example Google map, on HUD if possible.
Just wondering if other people have done this in the past.
Thanks heaps for your help.
