Hello there.
I need help.

I have a 2010 Subaru outback with a CASKA head unit running Garmaps navigation. there is a sticker on the back saying Windows CE.

Apparently they stopped using and supporting the garmaps, and when I bought the car in 2020 it was waaaaaaay outdated, and the agents just shrugged.

End of last year the Micro SD card with all the software on, corrupted itself and now I have no navigation.
I just bought a new Micro SD card and am trying to find software to load.

This is where I need help.....

Is there a free software program that I can load onto the SD card, and how do I do it.
I am not the worlds most computer literate person, so I need step by step instructions please.

Thanks for any advice.
Cheers
