Hi Ben,
The MFD 2 DVD will be compatible with the OE CD changer, but the Kenwood will not

If you opt for the Kenwood you will need a few extras
Harness
Fascia adapter
You can also purchase a bluetooth unit and an IPOD adapter lead.
Reasonably speaking you will never use a CD changer again if you have the Kenwood as it also plays MP3 on DVD's, meaning you can have the equivalent of around 50 CD albums on one disc
