Head Unit Swap

Can I directly swap my crappy A51809 HU for the newer (Non-JBL) A18806 (or whatever the number is) internal amplified one?

Looking at going from this

No i am not going to go aftermarket.

 

I have looked into this few days ago and it "seems" that the rear connectors are the same. If it works, let me know. It would be awesome to have stock looking HU with 6cd changer with mp3 & wma playback. That way I could put all my music in the HU's changer.

 

I have the factory installed 6cd changer with mp3. unfortunately, I think it sounds terrible. I usually never need anything other than a factory original HU, but this time I think I may need to go after market.

 

Yeah, now think of what you have but without an internal amp..... thats what i have. Turn it up past halfway and the music degrades horribly.
