Reminds me of the time when somebody added up the costs of all the parts to a Buick. Why buy $24,000 worth of parts when you can get them all assembled into a car for $8,000? (or whatever the numbers were)

I got it one piece at a time and it didn’t cost me a dime

More than just open source. We need a Linux based bogger that will show them how we play!

Here's a photo of one.
Raspberry Pi Zero for size, which costs $15 right now, plus a small LCD. Works with power meters.

Looks pretty nice. Seems to match the capabilities of the 520.
The navigation is basic. No generated turn-by-turn.
The cost of parts is probably reasonable. It’s using a dongle for ANT. The BOM for the Garmin units is probably low too. (The real cost to the developer is his time anyway.)
I wonder what the power consumption is like.

How's about using more than one device synced with each other? An e-ink device for showing turn-by-turn directions as well speed and heart rate alongside a larger-screen color tablet displaying a map for those moments you really need to look at one as well as for planning or changing a ride as you go?
Problem is, going down this rabbit hole, those e-ink displays intended for the Raspberry Pi are apparently fragile. You shouldn't place pressure on the glass is a common refrain I've discovered although I didn't look far and wide enough to see if this will always be true. I almost forgot to mention that the refresh rates on these can be quite slow. The specs for one seven-inch color display indicated a refresh time of twenty-five seconds.
I just picked up an Amazon Fire HD 8 lacking a GPS but can be made to work with an external bluetooth GPS receiver. Why not have one of these theoretical e-ink bike computers do double-duty as this GPS receiver?
