Garmin visit #2, GPSMap 78

Today Garmin introduced the GPSMap 78 series, an apparently major refresh of the 76 series long popular with boaters. While I only got to fiddle with a pre-production unit for a moment, I did learn a lot about the industrial design process behind it. The ID department in Olathe -- aka "The Skunk Works" or "Area 51" -- has a tool collection that would make all sorts of craftsmen and artists drool, but I'll save that story for another day. What's particularly notable about the exhibit shown above and below is how many design iterations were created and modeled for the 78, and how detailed they were...
And there was lots more to the process than shown here. The design software, for instance, could calculate whether the various shapes would float, but the design team also inserted appropriate weights into models and dunked them. (Incidentally, I lost track of how many different rapid prototyping systems the ID dept. has at its disposal, each apparently better suited for particular steps of the design process.) Garmin is justifiably proud of the ID facility and the talents in it, but made a special point about how it fits into the company's emphasis on vertical integration. Many manufacturing companies contract industrial design out to specialists, but it's hard to imagine how that could be as collaborative and as efficient as what goes on in Olathe. The evolution illustrated on this wall happened with regular input from the hardware and software engineers involved with the 78, as well as the marketing and sales teams. There are also processes in place, formal and informal, to encourage cross pollination amongst Garmin's several product groups, and to collect input from users via various channels, but those too are stories for another day.

This looks like an ideal form factor for an Android based device that would allow us to use the new boating applications that are coming out for smartphones which are terribly underpowered for continuous display usage and are not water proof.
Applications for managing checklists, inventory, POI information, etc.
This form factor allows for much larger batteries (than a smart phone), dedicated buttons for specialized GPS functions, waterproof, etc. With all of this I can imagine the following:
- A version where the screen is a touch screen, but the dedicated buttons stay.
- Android based operating system, in which you can switch between GPS function and Android applications that are purchased.
- Whenever you push any of the dedicated GPS buttons, whatever Android application is running is pushed to background and instantly replaced by the Garmin application.
- The Android applications have access do the GPS data, e.g. you can have your own anchor watch application rather than use the existing, etc.
- No 3G needed, but include wi-fi capability not just to get google android applications downloaded, but as well be able to download new version of garmins GPSMAP, topography updates, Active Captain POI (does AC mobile work without 3G signal?), etc.
What did I miss?
