Hi Dr_C, In reply to your questions it is not a homemade cable and it is plugged from our ipad (not iphone) into the external stereo speaker. We used this identical set up with the old app and everything worked fine. I guess we may have to uninstall then reinstall the new app to see if it works second time around. We are also having the problem with the cars slowing after weather incidents that has been mentioned in other threads. Again this did not happen with the previous version of the app so I guess this may be another reason to unistall and reinstall the new app.
