Your Garmin help, please

I'm looking for a GPS thing for two main types of ride:

Getting from A-B quickly and safely.
Exploring for a few hours at a time without getting totally lost.

I'm not interested in heart-rate / cadence / performance stats etc, and would rather not pay for functions I won't use, so I've been reading about the Garmin Touring.... A few reviewers say that although the routes are often very scenic, they are not usually the most direct for just getting somewhere in a hurry. One reviewer claimed it added 50 minutes to his commute just to include nice cycle paths.

So: is there a GPS unit out there that lets you choose between fast and direct (but cycle-friendly) routes, and pure scenic-route explorations (like the Garmin Touring seems to offer)?

Reluctant to use phone apps etc because my phone is shit.

Just to clarify - will a Garmin 810 do what I want?
Other than not including expensive / extraneous performance functions, obviously.
