Please please provide an update and keep it going:). I’m using it I’m with a furuno TZtouch19 thank you!! ### 1/5 — Does not work at all *2020-03-23, version 1.0.14* The app will not connect to TZ Touch 2. No support either. ### 3/5 — Navnet viewer *2016-05-31, version 1.0.8* The fish finder display shown on the App Store offering does not work with the current navnet touch mfd software. ### 1/5 — Can't view what you want *2015-09-20, version 1.0.7* You cannot view the plotter on this app. The fish finder screen is laggy and reads 1 fathom shallower than my TZTouch2. Total garbage ### 1/5 — Crashes on startup with iPad 1 *2013-05-19, version 1.0.6* Both furuno apps crash with our older original ipad. Works fine with our iPad mini. Please fix. ### 4/5 — TTZ Alarms on iPad and iPhone *2012-12-14, version 1.0.5* Very impressive app with very informative and readable screens. Only disapointment was the inablility to have an aubile alarm from the MFD on the iPad or iPhone, although the iPhone would vibrate, when vibrate was seected, when an alarm sounded. Al in all, Furuno and Apple have another winner, with some tweaking, it'll be perfect. ## Frequently asked questions about NavNet ### What devices does NavNet Viewer support?
