Loved the previous version Since I installed 2.4 it gives me a map rendering error and screen stays blank. I hope this is fixed soon. After uninstalling and reinstalling it still didn't work. Left it for the weekend and repeated the uninstall  download new version and install  now it works just fine. Don't know what the issue or whether there was a software tweek over the weekend. New version only works with some SD cards and insight of what they say maps downloaded with old version do not render even though they are in the right place and are seen by the program.
