This is the SONY DSX-S100. it features a integrated "tune" tray so that your ipod can fit neatly and safely inside. it also has a aux port incase your device doesn't have a usb. the curve that you mentioned is really easy to fix with a dash kit, basically go to best buy and they will tell you what kit you need. then search for it online for cheep. so far i have been really impressed with it. it works really great. you sacrifice the ability to play cds, but who listens to cds anymore. its 2011.
Thats kinda cool.
But yea if you want stock radio still then get an FM Transmitter, my room mate has one for his phone that plugs into the cig lighter and has a flex arm that holds his phone up so you can search and all that through the songs... Looks decent...
OR go aftermarket stereo... if you install yourself, you will need a Stereo install kit (The plastic that makes the square peg fit in the round hole lol)
Also you will need a wire harness, this allows you to take your stock stereo out, unplug the harness from the back of the stereo, plug that harness into your new one and then you have the tail wires that you wire to your aftermarket stereo... Very easy, match the colors get good connectors and heat shrink, then put the stereo sleeve in your install kit... pop everything in and your done!!!!!
