Just make sure you either get the radio code with an OEM replacement radio or can get it from a dealership for n/c, because you will need it to swap it into a different car and have it workable. The owner's manual says a dealer should supply you the radio code at n/c, but many now charge a fee to supply the code info. So, there may be an additional cost to another OEM unit.
I like the looks of the OEM units but they are very low power and not very reliable whether they be the Clarion or some other brand(s). In the 2001 I installed a single DIN Pioneer w/USB impute from Crutchfield for about $100. Way better power, sound, features, etc, etc, than the Monsoons but not with the OEM "quality" look. My other MklVs had double DINs and the only reason I haven't swapped those out is that they still worked and I had a couple PhatBox hard drive systems loaded up with a bunch of tunes.
