Cool looking car mount Russel!
Although I see that you are using a tape to pass on music to your car stereo.
I am very happy that my car stereo has build in line in.
If you ask me though I will never make a car mount for me. I have my iHP in my waste bag all the time! So all that I have to do is connect the ihp with my car stereo (with the bundled line cable) while my iHP is still in my waste bag!
If I want to change a song I have the remote out of the zipper of the waste bag and clipped to the seat belt
(always wear your seat belt)!
I can post some pics if you want...
