SD 3.6.3 on Android Galaxy S3 smartphone in planning mode

I was in Belgium a few days ago and for my return to UK had my first route (in Belgium) selected. I checked the route TAF and METAR reports without difficulty.
I then wanted to get an overview of wx conditions in UK so selected the "get weather for chart" feature and selected UK. That presented the colour dot symbols for the UK.

How do I return back to the map location that depicts the start of my planned flight, other than continuous swiping of my screen? I can't find a "back button" and pressing the "map scale" button at the bottom left just takes me to a random location, but at my default map scale (1:500,000).

I had to go and reload my route. I have checked the manual but couldn't see anything obvious mentioned.

Thanks
Tony
