Steel wheel control head unit?
 

Hi guys I'm very interested in getting a new steel wheel control head unit for my dad, and take off his old stock radio.

Steel wheel control HU seems convenient when driving, do you have any experience about that? Is it really so useful and necessary?

I'm now looking into Eonon, since I don't wanna break a bank, they declare to have up to 50% off now! hmmm... I'm struggling between D2208 with steel wheel control, and D2202, which is without it, and cheaper. Which should I choose, any opinion? Thanks!

Just got to know that they are now running a contest for world cup. Will send cool presents like flip down and headrest for the winner, I'm so interested, since I also wanna add these equipment in my ride. Not bad, I think I'll buy a D2208, kind of love at first sight!:D
