I had the GTA Car Kit for a while but I replaced it because they didn't honour the warranty on it. I went with this instead.
Car iPod iPhone Integration Kit for Honda/Acura - City of Toronto Audio, GPS For Sale - Kijiji City of Toronto Canada.
The best part about this one is that for an extra $60 or $80, you can add Bluetooth to it. So for about $160, you get iPod/AUX integration with Bluetooth.
