I see you have a bluetooth connection as well. That (White solution) is probably what I should have done (I did the $1K Aussie radio). I would have saved a lot of money and gotten most of the bang.
Keep us posted about what you do with your trunk release. It is arguable that you need do nothing. You should be able to open your trunk from inside the car or your key fob. With a dead battery, you'd need a jump from under the hood to get it open. I've considered just running the "pull cable" into the passenger area. Steve did a neat thing with the key being under the fuel door....
