International Dateline issue

I used this app on a passage across the Pacific Ocean from Panama to Vanuatu loaded with the maps for this area. On the whole the app performed well on my iPad 3G which has built in GPS. But the Achilles heel of this app is when you transit the International Dateline which cuts through Fiji and I assume it would be the same in the N hemisphere as well. This makes it impossible to easily view the islands of Fiji in detail as you can only look on one side of the dateline and if you want to look on the other side you need to scroll right around the world so that you approach the dateline from the other side ie W to E. Also your route line goes right around the world in the WRONG direction which is a safety issue as you cannot then do a scan down your route line from your current position to the next waypoint to see if there are any obstructions along your plotted route. I did not have this issue with the vessels built in Raymarine GPS chart plotter and iNavx really need to get Navionics to fix this issue.

Attn iNavx Support - Can you please provide an update on the status of the fix for this very important issue which is crucial for anyone doing Ocean passages near the Dateline.. The initial feedback I posted above is now over 5 years old. Thanks Steve. Dec 2018

Attn iNavx Support - Are you ever going to resolve the serious dateline issues with your app that I have previously reported above? An update would certainly be appreciated by the cruising community..Thanks. Steve Aug 2020

Don't bother

If you are a recreational boatie in Australia, don't waste your money and time with this. I was looking for a quality alternative to the Navionics ap. The only charts available for Australia that can be used with inavx appear to be the Navionics charts for a $140 pa subscription. You seem to be paying for a comprehensive instruments overlay that is very complex and way over the top for local pleasure cruising. I am not a fan of the Navionics ap, but it at least allows you to easily navigate at a reasonable price point.

Excellent app

Used this app in conjunction with predict wind for offshore racing in Australia. I have the navionics gold charts and maintenance of the chart data base has become much easier with fast response from supplier to any issues. Would recommend to all sailors.
