1. Perhaps for the unwashed masses....
Well, if you need it so much, and you think others do, learn how to code and write it. You seem to think there's a ready made market. I would probably make it Open Source and give it away for free and have others join in, but you can try selling it if you want. I'd suggest Android as the target OS.
In April when I asked for suggestions to include everyone's needs for a much needed update to BC, so I could present them to Garmin and point out why Garmin holds an important marketing tool in this software. What I got was one guy calling me names and a few others saying everything worked for them right now so they don't care. I thought, what happens when you get a new computer or a update to your operating system or a new device and then it doesn't work.
So I started with Garmin CEO Clifton Pemble in Kansas with my request, the need and the marketing advantage for Garmin. That prompted a phone call from the head of automotive (don't remember his name).
About two weeks ago, (four months later) automotive told me an update to Basecamp was going to be released. I don't know when or what will be updated - but it's a start.
I'm sure the guy that called me names and those that said everything is working for them so they don't care, won't be doing the update when it's released since they have no need for it.
I wonder why Garmin refuses to update BC ?
Garmin clearly has the programming staff to handle a from scratch redo.
