I have the pioneer avh bt2500, good stereo for the price IMO. The patch lead will sort out your steering wheel controls (same one I bought). On the after market stereos, the sound volume is low compared to the BOSE, so might be worth doing the 'Buster mod' (search the forum), or as I'm not confident in my ability of cutting the correct wires, buy a'booster' that attaches to the wiring harness to improve volume. Hope this helps
