Hy.
Today I started thinking to use iPad as alternative for some chart plotter device such RAYMARINE A70.
What i figured out is that I should have GPS app (iNavX maybe) + maps (Navionics Mediterranean) + some IPG device with NMEA protocol (Maretron IPG100 or cheaper Digi Connect® Wi-SP) + depthmeter or echosounder (Maretron?) which is connected to NMEA device.

My question is, if above configuration will work and what depthmeter I can attach to Digi device? Maretron is too expensive, but it has all the features + iPad app.

Will iNavx show depth if ipad is attached over WiFi on some NMEA depthmeter device?

Will the iPad built in GPS will be enough for sailing, or I should attach some external (Bad Elf GPS maybe)?

Thnx!

Your best option for interfacing a NMEA-0183 sounder and/or GPS is the iMux from Brookhouse. It will accept 4 NMEA inputs and output to both a PC/Mac, iNavX and other NMEA listeners (i.e. Autopilot, DSC VHF, etc.)

iPad 3G has a good GPS receiver.
