New 2013 Package II owner

I recently got into a 2013 package II and was looking to do a few upgrades and wondering if it were possible and if anyone on here could point me in the right direction. Mainly, I wanted to swap the headlamps for the package V headlamps (Xenon and LED) and was wondering if this were possible?

In addition - I have the touchscreen with backup camera installed and was wondering if I could buy some sort of plug in module/adapter or upgrade to include the entune functionality (is this just software?), or navigation (I know that I would need to install a GPS antenna)?

Also, I don't have a garage and unfortunately I have a tree over my driveway that spits a sap mist all day long. I was considering getting a nano coating for the car (C Quartz Pro) so that I don't have to continually scrub this car. Does anyone have familiarity with these coatings, their effectiveness and their cost?

Thanks for all the help, this is such a great forum!
