Someone started a thread earlier about hooking up an external HD to their headunit and playing their MP3's. That got me to thinking about hooking up my laptop to my HU wirelessly using Airport Express.
Now before you PC guys roll your eyes and close this thread, keep in mind all this WILL work with PC's too.
I don't know if it's been done, I'm sure it has somewhere, but I didn't research on it.
Onto the pics to show how I did it.
Hook up your power inverter
Plug in your airport express
You can see where the interverter goes in and where the audio cable from the airport express goes in.
Full shot of everything. A good mounting spot will have to be found.
Playing my itunes from outside of my truck.
I thought it would be cool for car shows, being able to control your songs from outside of your truck.
Another advantage is being able to leave the inverter and Airport express in your truck and simply just get in your truck, open up your laptop and push play.
It has it's pros and cons. Not something I'm gonna do because it's easier to just use an ipod or play my burned CD's, but might be helpful for someone. (Plus I need my airport to run my home network)
