Alright, well I would say that MY electrical know-how is slim to none, as I totally don't understand anything in your second line, however my dad is an electrician, and he is helping me with it, I'm just the one who is good with their hands and doing the research.
I like the idea of having the power when the key turns on, but let me paint you a totally clear picture (as best as I can).
When my cable comes, I will have an AUX cable coming from the back of my REC nav's SAT port (http://www.tss-radio.com/products/chry04-aux-slash-s
) feeding into the glovebox, and have that plugged into the router. It's an Apple Airport Express, this is for Airplay purposes. This is where my issue is.
- I get in the truck, and start the car.
- I pull out my iPhone, it connects to the router. The router takes 80 seconds to boot up.
- I pick a song, hit play, and put the phone back in my pocket, switching songs or playlists as necessary
- I pull into a parking lot. I turn off the engine, the radio is still playing. The router should still be running, music still playing.
- 1 minute later, I turn the key and start the car again. The router should STILL be on, my phone still connected, and my music still playing.
- I continue down the road, go home, and pull into the garage.
- I park the car, turn the key off, and exit the vehicle. Everything including the router should be off.
You're talking about delays, it would make the most sense that the router runs for 5 minutes after shutting the car off, in case I'm just running into a store or something, and I don't have to wait around for it to boot up.
