Displaying KMZ file + my location in Android Google Maps application?

This is probably a newbie question, but I don't know anything about GIS.

Someone sent me a GPX file that I converted into a KMZ file so it's displayed in Google Maps.

It works fine when viewed in a browser, but I'd like to display it in the dedicated Maps application in Android so I can view the KMZ route and my current location at the same time so I don't stray away from the planned route when going for a ride.

However, Maps doesn't like pasting the URL with the KMZ file.

Here's a screenshot:

Is there a way to see both a KMZ route and the current location?

Thank you.
