JUST PULLED THE TRIGGER ! 2015 RT Limited with 2,550 miles ... Ima newbie

[Sarge]

Test rode it and was impressed. Deb, my wife, can't ride as a passenger on our Kawasaki Voyager anymore, due to a major stroke last Feb. Sooo, it's either give up riding all together, or, sell the car and bike to buy a Spyder. She said go for it. For those of you who replied to my previous post, Thank You! The dealer said the previous owner has a warranty that is transferable for $50, but haven't heard from either of them yet. I'm a newbie on all this, so, expect to see a lot of posts and (DUMAS) questions from me!

1. Can I check the firmware version on the bike?
2. Is there a cable and app that will let me do #1 OR other "stuff" like switch to LED's?
3. I love the headlight modulator on my Voyager. Is there one that works on the 2015 Spyder RT Ltd? (I know about the shutter)
4. 3rd brake light with modulator suggestions?
5. What accessories should I look for first? Skid Plate? Etc ...
