In the old days, you wanted an App in order to access the GPS.
Today, the browsers have access to Q10's GPS. Thus an app is no longer required. iPads work on the same principle when Crapple maps were introduced.
Take your Q10 browser and bookmark https://maps.google.com. I'm amazed how fast it's able to find my current location. For traffic, tap on the layers icon on the upper right for traffic. I supplement this activity by looking at the regional webcams to plan my drive home each day.
I use a site called goodereader.com. This site has a link to download a DDPB installer that you will use to install sideloaded apps. They also have a vast library of android apps that are available for sideloading. They have true google maps and many other fantastic apps.
