I'd just like to follow up on this post after about a year since the install.
The aux port is amazing! It still works wonderfully and sounds great even with the stock speakers. The radio still works fine, though sometimes it only plays out of one side. I believe this is because some of the crappy plastic still melted under the heat of the soldering iron despite all my efforts to prevent that from happening. I wish I could find an all metal version of the plug to put in. I'd like to add a small amp and set of decent speakers, I think it will really bring out the sound
