Hey,
I actually picked up that kit and it has been amazing for the past 3 months since owning it. That was my first purchase for my 04 TSX and I haven't had any problems with it thus far.
I would recommend changing out the AUX cord it comes with, but other than that, do NOT cheap out on an AUX kit. It's really easy to install as you take out the empty dash box and pop it in with the use of your phone's front facing camera.
I've heard stories of people buying cheap AUX kits and it's lasted them a month or two before crapping out on them.
