The V is SRV stands for VFR. Basically the story is that Cirrus realised that while they had a great aircraft in the SR20/22 they were never going to compete with the C172 etc in the flight school market because they were just too expensive and flying schools were not interesting in paying more for aircraft that just flew a lot faster than its competitors.
So rather than come up with a new model they ripped out all the stuff that made it IFR, ie the Garmin 430 etc and sold it for $40,000 less or something like that. Doesn't make much sense to me though since while PPL training is done VFR I would have thought that most flying schools would have wanted the option to do instrument flight instruction as well.
In general I find the older Avidyne systems (which I'm assuming this had) quite simple to use, unlike the G1000 which if you don't know what you are doing can get you in a pickle quite quickly.
