Kinda strange from what I've been reading here, but my old iPad2 with Bluechart N. America charts already installed & AC downloaded is still working fine. I also just had to replace my iPhone
, from a 5 to a 7 running iOS 11.2.1. The Bluechart app was no longer available as has been pointed out, but I downloaded the free AC app from Garmin and it allowed me to install my previously purchased N. America charts which appear to be functioning just fine (w/AC overlays).
Am I missing something here?
