I have a 2013 Octavia with a Bolero radio, obviously no sat nav. I’ve had an update which allows me to wirelessly connect my iPhone to the radio and through the media page have CarPlay. Now I can have Waze, TomTom Google maps on my radio screen along with all the other CarPlay apps and keep all the original features of the factory unit which I didn’t want to lose. I can connect either through a usb cable or wireless. All for less than £600. 

Are you talking about this kind of thing?

Yes, this is something similar 

How is the spelling with this unit. I have tried and Android head unit and an AI box and spelling was a hastle. Several seconds delay and always spelling wrong

This is the unit I had fitted, I've had it for over a month and it works well. More importantly all the original Skoda features are saved.
