MM19 Sat Nav - Over Air vs Download

[JonathanP]

Does anyone know the difference between an update done via Wifi on the Sat Nav itself vs one downloaded to USB.
The reason for asking is when I did a Map update via Wifi in the car the update was only around 200mb in size and took 15 min max.
However when downloaded from the web it's about 1.2Gb in size and the update took nearly 2 hours.

Does the download from the web include more than just the map update?

About 12 months ago I updated my Corolla satnav via wi-fi, the updated version didn't have any speed camera info or speed camera warnings.  I had to download to a USB memory stick and install from there to restore everything.  I installed the latest update a week ago.  It took 1 hour and 10 minutes in the car and that was on top of the time it took to download from the Toyota site and unzip.

Jonathan, I believe OTA only updates UK mapping.
