I used to do upgrades all the time as the existing stuff was marginal. Now the installed gear is so flexible and good that I leave it alone. My one "upgrade" is to use an external XM receiver fed into the aux on the car system. I already had the XM so it was a no cost fix. Just pop the unit out of the home base and put it in the one in the car.
