Purchased app yesterday and initially worked perfectly, then my iPad wouldnt show position on SeaNAv. Strange. I emailed Steve Bennett @ Pocket Electric (the developer) and I had an email back from him this morning. Theres a known bug in the llatest bersion of iOS software that prevents the iPad from accepting location from the extenral GPS (in my case, a Dual). The fix is on the iPad: (1) turn off location services on iPad; (2) reboot iPad; (3) wait 5 seconds and turn iPad on; (4) turn location services on. This may need to be done whenever the problem reappears. Lets hope Apple fixes this soon. Anyway, the SeaNav app is outstanding and a real bargain for the recreational boater, in my opinion. And the quick, accurate and friendly tech support seals the deal for me!
