yep that are my concerns, operating the hu via touch screen while driving... I might actually end up with single din Alpine I had before plus some BT. At least the bottom din can be used for all the outs.
anyway, I have had a look, and I think they are bit overpriced for what they really are. Only one unit (I think the one with the dvb-t tuner with double antenna) could run both of my navigation software from SD card. For, me being the website developer/designer, the UI is shit, though it's not that sluggish as I've expected. But the interface for RADIO source is horrible. It played music from my iphone over BT no problem, seems like everything worked well.. it's just not going to be the selling point once you decide to sell your car..quite the opposite I dare to say. to pay 550$ for that single unit is just too much to my liking, I'd rather get that JVC.
But all my upgrade dreams got hit once I've returned to the car. I couldn't start it up, different errors shown above the odometer reader but the electronics were running all fine...I thought this one would need towing. I might add I'm not a NRMA member.. but I became one for 275$ + 153$ the battery I feel like I got myself a bit ripped but at least the lady was so kind that instead of one year I got two for that price (I must've sounded desperate

).. she broke it down for me sayin it's the 99$ per year plus as I'm in emergency within 48h, that's 170$.. bud she gave me an extra year. it doesn't feel like winning the lottery but at least it wasn't anything worse with the car.
