Down to personal preference. So many phone manufacturer and after market kits around the choice is pretty much endless. Personally I have a Parrot kit so don't even need to see the phone. It sits either in a pocket or in the centre console normally.
Not my photo jack nicked it from the linked wiki but I just rest my phone on the sliding bit when it's pulled all the way forward. Then slide it back a little bit and have the other phone free standing in the gap
If I'm in a hurry I put it in the slidey drawer near the Cig lighter.
If I'm navigating somewhere I use my Kenu Airframe which is way better and simpler than many of those ebay cradles/holders that I tried in the past. Although the Civic's dash and air vents are kind of rounded it still works ok.
