Ladycat, here's how you do it.
1. go to "settings"
2. click on "more" in the top navigation bar
3. click on "application manager"
4. should show downloaded applications, scroll down to Chrome
5. Click on Chrome, and uninstall updates
6. Then, scroll down to maps
7. Click on maps and uninstall updates
8. Resume navigating on what is undoubtedly the best navigation application in existence.
Why Google is trying to switch users to the new google maps is beyond me. Bottom line...it's just not as good as the default application already installed on my phone.
