There are many different flavors of G1000 avionics in airplanes. Just because it says Garmin on the bezel does not mean it has the exact same capability in different airplanes. Thus, because you have a G1000 it has full VNAV capability is not correct. Depending on the airplane and the certification of the AFCS you may have some feature only found on airplanes with advanced automation. I.e. you will not have the advanced speed control in airplanes without an auto throttle and thus your VNAV climb capabilities may be FLC, VS, or Pitch modes only. This means it is still the pilot’s responsibility to manage the airplanes modes correctly on an RNAV departure with altitude and speed constraints. Generally, the VNAV descents are a little better, but the pilot must still manually manage things with less sophisticated automation. Move up to an airplane with a Garmin 5000 and advanced automation like the CE 700 Longitude then yes it is fully capable. At least it should be, but Asobo built it with a very basic Garmin like system that only has very basic capabilities. You will need to wait until a third party developer takes on these advanced airplanes.

The other issue is the basic G1000 in MSFS is still significantly bugged. In that what they did chose to model is not correct. Not to mention the thousands of features they chose to leave out.

Well, his question was, does the G1000 have VNAV and ILS capabilities, and the answer is yes. You don't need speed control or autothrottle to have VNAV. Heck even in planes with VNAV and autothrottle, such as the TBMs, you need to pay attention to the speed depending on what mode you're in. You can just as easily stall an airplane with speed hold as one without, perhaps even easier. 

even the trusty GNS430 (mid 90s?) equipped SEP:s that I fly offers basic advisory VNAV features. I think it needs to know planned TAS in order for it to work and route, obviously.

I generally flick "Otto" on when I step out onto the wing for a cigarette..  easier than pausing the sim when flying in OnAir, because pausing the sim increases the time of the flight and therefore my rental costs 🙂

Fly the C172 on autopilot? Absolutely. Once I get to cruise altitude. The first thing is, when ATC hands you off to the next controller, I tune it, but I don't contact it. The ATC window will continue to update the controller frequencies, but won't 'bother' you (a very old trick). Just select the 'tune to xxx.xx' every now and then to listen to what is going on. I then must turn on the autopilot as I usually have many things to do. Take out the garbage, make some coffee, surf the web (fs forums?) and other important things.

The C172 can not monopolize my time by expecting me to sit there and hand fly it for 300 miles. I would never get anything done. Once I get to my destination, I will once again contact ATC (who is none the wiser that I have been ignoring them 😂) and then have some fun flying the approach.

He also said like a 777. So the answer is more of yes it has VNAV but in the C172 it is not like the 777.

This conversation is going all over the place. There were some who answered the OP's Q with a simple Yes. Bravo.

Yes.. G1000 would do the VNAV/ILS. Just like the Garmin 530. It even does WAAS LPV (VNAV without ILS)

the challenge of Auto VNAV in aircrafts like 172 is like someone mentioned the lack of Auto throttle. The AP would start nose down when it hits the GS/LOC FAF (Final Approach Fix )but the speed would increase since its not controlling the throttle.. So you have to set the right RPM at different phases of the approach.

e.g. when flying the twin Piper Seneca at around 2200 when it hits the GS/LOC (FAF), I just drop the gear and and It would descend at 3degree with no change in the speed. Different aircrafts have different gaits and you need to know for a specific aircraft the various settings you need to use like this for Mooney aircraft

See the difference between Approach level and Precision descent. At FAF, Gear Down and 3 bars (degrre down on the attitude indicator) . That's it. No other change.No mucking around with the throttle.
