Here is the list of parts, and the websites where I found them. I bought everything from L-Com. You will need a male to male 8 pin MINI DIN extension, I do not have the part number because I ordered the wrong one, I got male to female. 1 adapter, MINI DIN Female to Female, part number MD88FF. The hook-up is self explanatory. If you like the IPOD holder, it is from KUDA.
