Yes, I used NCSexpert to recode with after installing the aux port. I've read almost everybody is complaining of the volume issues even with factory installed. I have read everyone of the threads but yet no one has the answer but I figured something to do. I was at radio shack yesterday and purchased a 3.5mm rechargeable amp, it's the size of a half dollar piece, and it works perfectly. It is rechargeable so that will be a pain but it actually makes my iphone sound better than cd and louder than the cd/fm.
