I have just swapped my stock CD&Radio with a new unit. I selected a Pioneer AVIC-HD3BT (AVIC-Z2 in the US). This is a unit that can play, Audio-CD (and stores them on the Harddriver), MP3 from CD-R, DVD movies, it has FM and AM radio, GPS navigation system with maps for all the Europe (in my unit), voice recocnition, voice command, voice guiding in navigation, Bluetooth for handsfree mobilphone operations and lots more. I have also added a USB adapter so I can play MP3 files directly from a USB-disc or USB-memory pin.
The installation was easy, but you need to get a new face panel for your car first. I ordered a orginal 2DIN Face Panel from my local Honda dealer. Part no 08B00-SAA-611B for my Honda Jazz 1.4LS GD1 (2007). And I have this automatic (electronic) AC system.
Pictures of the unit can be seen here:
