If anyone is looking for a reasonable but handsome replacement for the stock Infinity (Harmon-Becker) unit, the Blaupunkt folks make some great models that require almost no modification! As you can see in the photos, the main connector interfaces are the same (middle and bottom modules) You do have to remove one double gray (located in corner position) wire to keep the mute feature de-activated. I removed the contact with wires intact in case I ever want to replace the original unit. The best feature is that it plays mp3 disks which can hold hundreds of songs each, thus reducing the quantity od CDs carried! You will also need a German car antenna adapter available at best buy or ebay.
