Has anyone found any issues with the latest update to Navigon for iphone? Have iphone 5, and connecting in my car through Jabra Tour...it previously worked reasonably well except sometimes the directions would get a little chopped (ie. Turn right in _ _ _ _ miles)...but in their latest update they mentioned "improvements" to bluetooth...it seems they may have inadvertently caused some new problems...now after almost every spoken line from Navigon, the voice says "CALL ENDED". This NEVER happened previously, and it seems whatever alteration was made to bluetooth handling has caused this. Anyone else find this? ...I love Navigon on iphone, but this bug is awful! Thanks!
