Crutchfield is an awesome company I would recommend if you want to upgrade your head unit. They sell 'retro' styled radios, but you'll be paying around $350 to keep the retro styling with the modern features. Although when you order from Crutchfield they'll provide a pigtail that will plug into your factory harness so you don't have to cut up a bunch of wires

All of their radios have an aux input (on the rear of the radio so you would have to plug in a cord and then run it under the dash and then into the cabin) but not all of them have bluetooth so look at their descriptions.
If you don't want to get sub I would recommend getting
this radio for it has 25rhms and 45 peak watts vs the factory radio which I would estimate it puts out 15watts peak.
If you think youll want a sub go with
this one because it comes with 6 channels instead of the 4 like the previous one (the extra 2 channels are for the subwoofer which will make the wiring much easier instead of splicing into the other channels to your signal output.)
If you dont want to go with an aftermarket head unit an aftermarket amp would work wonders. A small low-profile preamp 8" subwoofer under the front seat or one in the trunk will be a night and day difference.
If you have any questions and or need an opinion on anything just let me know.
