I just installed the BEC106 on my 2009 TCH. Removal of the radio and console were easy thanks to Jbagri and others on this thread. Some additonal comments based on my experience:
When removing the radio, temporarily re-install the shift handle which acts as a soft stand while you are pulling the unit out of the dash.
Apply blue painters tape around the edges of the radio to help prevent nicks if the radio gets bumpted during removal.
I removed all the connectors behind the unit in order to maximize as much access to the R10 connector. They're mostly color coded and were fairly easy to remove and re-install.
I had no luck with the CD audio cable. Pins were too small so they didn't lock in, and, the wires were too soft.
Instead, I purchased a female DB25 connector kit from Radio shack. It includes the DB25 shell (not needed) and 25 female pin 'crimp' style connectors.
I also used telco wire which is stiffer and figured would help with the insertion into the R10.
I soldered the ends of the telco wires into each of 4 DB25 female pins.
Now the tricky part - make sure your solder joint is clean and minimal. Remove any blobs with a file. Further, the center of the DB25 pin has a small bulge and will not fit through the connector, that too will need to be filed down around all sides. I broke a number of pins in this attempt, but you have 25 chances to make it perfect. Take your time with this and be patient. You don't need to remove much - a millimeter or so will suffice.
I then soldered the telco wires to the BEC106 cable and applied wire tape.
During the insertion, I used a Sub-D insert/extract tool (also from Radio Shack) to help push the wire down into the connector.
I reconnected all the other cables and re-installed the radio. The camera came to life when I put the car in reverse. During this install I also installed an Ipod integration module. See the Ipod thread, works very nice as well.
Many thanks to all who contributed to this thread, I would not have attempted to do this otherwise.
