I agree that's a viable option. It's actually similar to what I started with. Even my Samsung 3.7" screen was big enough to navigate through everything I needed to. It's easier to do on the Pioneer screen, though. I think I find the larger screen to be a bigger benefit than you do. There's also something nice about having it integrated. So, for me, it goes beyond the functionality. We'll see how I feel after some time using the navigation...see if it meets my requirements of finding crap and getting me to it! I also wanted to get bluetooth phone/audio, and I also wanted to play with Pi
