Hi, I wondered if the GNS 5870 MFI external GPS is supported too by iNavX. Because this GPS is certified by Apple and according to a Dutch marine webshop therefore supports all official ios apps. See here for claim including navionics, the charts that I use on my ipad2;

The advantage is that this gps uses bluetooth, and the antenna can be put anywhere in your boat for a good signal reception. Especially handy in a steel boat, which is a cage of Farraday blocking signals. Using the Bad-Elf which is inserted into the ipad itself, is less usefull when it just lays on the chart table.
