for those who JUST changed the HU
 

hi everyone,

I have a simple question. I have the Baden HU...will changing the HU out with an aftermarket allow me to continue to use the stock USB and AUX ports?

will changing the HU itself provide me with an improved sound? The stock system isn't too great. Thanks

You will more than likely lose your OEM bluetooth function / USB function / Aux port. I'm sure there is a DIY to regain those functions with an aftermarket HU though, so if you're feeling crafty you can easily get the functionality of your stock stuff back.

HU can increase sound quality, but I wouldn't say it's the most significant change you can make to your car to improve the overall sound quality. It's a minor sound upgrade.
