No red lights, code you need to know, etc required on business cd head units...just replace and go.
Couple things worth noting:
- You can install subs without changing the head unit.
- You can get OEM AUX intergration with an OEM head unit, but need one produced more recent than yours
There are good alternatives to a single DIN aftermarket head unit that will get you what you want while retaining OEM, or atleast the OEM look.
If that interest you and you want to know more, let us know what you want, function wise, from a setup and we can make suggestions.
