When I tried to use delphi again the CDP+ (with 1423 fw) again needed updating and it updated to 1513 fw. When I connected a CDP+ (with 1530 fw) to WoW, the fw also needed to update and fw changed to 1423 fw. My CDP+ came with 1530 fw, but when connected to Delphi it was updated (to 1530 fw), to work correctly.
In my case I use Autocom CDP+ with Delphi cars 2014.R3 and WoW! 5.00.8R2 apps and I have this kind of a problem. I have been reading this forum for some time and managed to learn quite a bit about automotive sw.
