Im looking to build an Ipod dock specifically for my car. Ive been looking at the ones at places like Best Buy and Circuit City and they are 200 plus bucks. I found a guy that sells the little connectors to plug into the bottom of the IPods and found pin out instructions for it also. The diagrams can be found here. I want to connect the power from the car to pinouts 19 for the positive and 29 for the ground so the IPod will charge while its in the dock and run wires to pinouts 3, 4, 5, and 6 and connect it to a set of rca audio out connections. Now for the difficult problem Im having. I know this configuration will work (or at least Im 99.99% sure) what size fuse should I put on this device to make sure just incase the power surges I wont blow up my IPod. Any comments or suggestions would be helpful. Im going to actually make a fibergass or plastic (havent decided which) docking bay for the electrical and everything to go in and make it connect right next to the ac controls (similar to the tach adapters you see for the mustangs). I think it would be nice to just jump in the Mustang slide the ipod into the cradle put the radio on aux and enjoy some good music. If all goes well I may try to sell it if anyone is interested.
