JUNK!!! What a waist of my time. Did not work, hope they are reading these reviews. News flash, there is a huge android market out here.
Very limited in the instruments that it interfaces with. I have a new Echmap 50dv and it would seem that the WiFi function is pretty useless. It doesn't work with Helm nor will my Android phone talk to it. Garmin offer up BlueChart Mobile as a panacea but that only seems to be available for Apple products. I kinda wish I knew about this prior to purchase
Update Firmware!!! App Does Work!! Was having issues with the app. It was stuck on searching networks for devices yet I was connected to the network the device generates. I thought to try updating the firmware on my father's GPSMAPS 547xs by downloading the latest updates from Garmin to a microSD cards and popping it in the unit. Once the firmware installed the app instantly recognized the unit. Works awesomely!
Works great with my 741xs! I did have to update my chartplotter firmware and then turn on the built-in Wi-Fi on my plotter and attach my phone to that.
Works Great It works as it's supposed to. I use it to plot a course while my father is driving the boat. I'm out of his, way he's out of mine.
App works great if you're having trouble linking to your unit make sure your unit has the proper software update free from Garmins website and wifi turned on.
