Congrats on passing your technician test! I love having 50+ watts of 2M mobile power when I'm in the back country, definitely gives you a bit more piece of mind when the family is camping with you in the event things go pear-shaped.
I use my 80 as a repeater up on a ridgeline while I'm hiking with the HT in my backpack.
I'd advise looking for a mobile radio that will fit in a single DIN stereo mount (as well as cross-band repeater ability so your Baofeng can really stretch it's legs), then find a cheap single DIN stereo to replace the factory double DIN unit- both the 2M unit and the stereo fit nicely in the same hole. The 80 already has a cooling fan circulating air behind the dash, so no overheating issues.
I've got this setup in my 80 and I love it!
