I am thinking about adding a tablet to the SE when the little storage place is on the top of the dash, but I'd hate to loose that storage spot. Illegibly you can plug in to the aux plug for sound. A nexus 7 has been used but I can't figure out if the GPS is on board the nexus 7 or I would have to get a cell phone contract for it. I'd like a bigger nav screen for sure, and the guy also hooked into the OBDII, I assume with BT and uses an app for some digital gauges. A lot of fluff I know but my radios screen is nackered, and I can't read it. A replacement radio is too expensive right now, and I can't find a replacement LCD anywhere. One day I guess when I start wearing pants with more pockets.
