My last 4 cars before my first Model X were all Ford Escape Hybrids with the Ford Navigation. For nav system reference, I owned a 2008, 2009, 2010, and 2012, all with OEM nav system and data from SiriusXM. Several things that Tesla is missing that I loved about that nav system are:
1. In-route Navigation - I'm on a road trip with final destination already programmed in nav system. If I wanted a coffee, I could search for Starbucks and I had the option of listing their location by simple proximity OR along my active navigation route. Once I selected the location, it added it as a waypoint without cancelling my trip navigation.
2. Weather Maps (RADAR) - I could instantly check to see if I was driving into bad weather.
3. Weather Maps (wind speed and direction) - The whole reason I owned a hybrid was to get better fuel economy and being able to anticipate headwinds, tailwinds and crosswinds along the way really helped. Knowing I had a tailwind or headwind allowed me to adjust my speed to compensate for fuel consumption.
Both Ford's nav system and another nav system I use called Navigon (a Garmin iOS app) allow me to toggle ON/OFF they types of businesses (icons) I want to see pointed out on the map. This allows me to limit the clutter on the nav screen while ensuring that I ALWAYS get to see the business types I am most likely to use.
KEY POINT: Tesla is missing a HUGE opportunity to satisfy a basic customer navigation function (waypoints) while potentially monetizing their "big screen" infotainment ecosystem. Just like Ford/XM and Garmin have done with their nav systems, Tesla could profit from companies, like Starbucks and others, who want Tesla customer and are willing to pay Tesla to get their logo (locations) overlaid on Tesla's navigation maps. In the same way that Tesla provides information on Supercharger locations when you tap on the Supercharger icon or how Ford/XM and Garmin provide additional information (address, phone number, hours, fuel prices,etc.) by clicking on a merchant's logo on the nav screen, similar functionality in Tesla's nav system would be a profit center for Tesla and a huge resource for Tesla owners.
