1) How much heat is being produced in your center console? I assume it would be less than a stock AE since you removed the power supply.
2) How long does it take for the network to become available after you start your car?
3) Does this method work seamlessly like Bluetooth does? Whereas you pair and set it up once then all your sound from videos, games, music, and all apps gets streamed, or is it done only on an individual basis like when you launch a video, you then have to touch the airplay button and select the airport as the device each time?
I'm interested in doing this because I would like the uncompressed sound quality that Bluetooth cannot offer.
