The fact that this survey was sponsored by radio manufacturers and the NAB should instantly tell you what the results are, but it does contain a few interesting factoids 

According to the poll of almost 7,000 people, nearly 90% of car buyers think a radio should be standard in any vehicle. (Isn't that already the case?) The questions were asked of drivers in the U.S., Australia, France, Germany, the U.K. and Italy, but not Canada. 

Many say the biggest add-on they want isn't Bluetooth or track info, but rather the ability to change the station using voice controls. (Have to say I don't think I would use this even if it was in my car.)

And despite the ongoing popularity of services like Sirius XM, most agree they simply don't want to pay for what they listen to. 

"A clear majority don't want to pay for radio – 91% say it is 'important' that radio should remain free to listen to – as it is currently via analogue and digital broadcast radio tuners. The importance of free-to-air radio was highlighted by motorists' concerns about data charges for streamed content: a clear majority (71%) of those who currently listening to audio via their mobile device say they are 'concerned' about how much data they are using."
