After many years of using OsmAnd, a much shorter time using Maps With Me and  for the last few years Guru Maps , I went back to OsmAnd last week. It can finally export GPX also on the road to feed my old Wahoo Elemnt Bolt which is still one of the best devices with its low energy consumption.

OsmAnd can now even create an overlay with Google Earth map tiles by going from Menu > Configure Map > Map Source > New

I was only struggling to import POIs from Google Maps or iOverlander but even this works when using Open Location Codes or

Plus codes are designed to be used like street addresses and may be especially useful in places where there is no formal system to identify buildings, such as street names, house numbers, and post codes. Plus codes are derived from latitude and longitude coordinates, so they already exist everywhere.[5] They are similar in length to a telephone number (e.g., 849VCWC8+R9) but can often be shortened to only four or six digits when combined with a locality (e.g., CWC8+R9, Mountain View, California).
