Hi guys- I have a Lexus RX350 Ultra Premium Package 2010. I am having a small technical issue, that I once knew how to fix, but have forgotten. My GPS works perfectly fine, however the issue is that when I view the GPS screen it was a detailed view of the map in the past. Meaning I was able to see each all the streets that were around me and the streets that I was driving on. Now when I see the map, it is a larger scale view, where it shows me the city, I am in, and the other cities around me. I know that there is a (+ and - )button that allows you to scale in closer showing the streets. When I do that it scales in closer, but as soon as I turn the car off and start it again it goes back to the city only view, not streets. I could not see a save option unless I am totally missing it.

Any help would be appreciated.

Thanks!
