i just purchased a mazda 3s-touring two weeks ago. Is it possible to add the stock navigation system in if brought to mazda for installation? Additionally, can I have the HID lights that come with the grand touring installed???

Yes it's possible to do both, however both of them are very cost prohibitive. Parts alone for the NAV system are around $2,000 and the entire wiring harness in the dash has to be replaced, meaning you have to remove the entire dash board.
The HID light housings are about $800 each plus bulbs/ballasts, plus money for wiring and the switch if you want to try and get the levelers working. You can get an aftermarket kit for $200-400 and use that in your halogen projectors. It won't look as good as HIDs in HID projectors, but it'll still be better than halogen.

ALL aftermarket HID kits are illegal for on road use in the US. That being said the biggest problem with HID kits is that people put them in reflector headlights instead of being projectors where they should be, and the result is a great deal of glare. The halogen projectors on the 3 do a pretty good job of cutting off the extra light and not blinding people though so you most likely won't have a problem. If you get an aftermarket kit then just try and keep the ballasts hidden a bit so they're not obvious. Then if someone (inspector/cop) mentions that you have them point out that the 3 comes from the factory with HIDs... problem solved.
