thinking about a new Garmin head unit. Bring me up to speed

[sailorboy]

So I've been a Garmin guy for several years now, and since I don't want to learn a new system, I guess I just want recommendations for an upgrade within the Garmin world.

I've had a trusty 520 edge plus for at least 5 seasons now and just wondering if it would be worth it to splurge on an upgrade to that, and if so, what model?

There are so many more options now than the last time I thought about this issue so I need help.

It's probably easier to say what I don't need than what I do so I don't need power (though I assume most of them do this anyhow). I used to use a HR monitor but lately have not bothered.

I suppose a larger screen is probably warranted given my presbyopia which would allow me to put the most important data points I want on the first couple of screens. Beyond that, I don't know what I want.

Ease of set-up and adjustment would be good since the 520 is still difficult to re-connect to bluetooth whenever there is an issue. Not sure why that happens from time to time.

Battery life is somewhat important since I don't want to have to charge it every few rides.

Thoughts?
