My needs were similar to yours, and I went with a Kenwood double-din non-DVD unit (DPX-500BT.) You can follow the link in my signature (it's on page 3.)
Great sound from the unit, and has all the features I need (Bluetooth for phone, USB/Aux input, iPod/iPhone controls) and a lot that I suppose I could use but don't (pandora, I heart radio, etc.)
The only downside is that the display has a very flat, slick surface that reflects sunlight BADLY! So badly that during the middle of the day the display is almost impossible to read. It may just a be fluke of how high the display sits in the 4th gen T4R but I can't recommend this one for that reason alone.
I have my display colors set to the brightest white colors possible, and with that, if I'm wearing my sunglasses, I can barely read the display, unless the sun is shining directly on the screen.
Having said that, I've decided to live with it for now, it's not that big a deal and I've gotten used to it, pretty much.
At night or in dim light/cloudy conditions, it's fine. The unit has great controls and the sound is awesome.
I think the screen's main problem is how flat it is. If it had some more curve to it I don't think the reflection would be so bad.
I bought mine through Crutchfield and installed it myself (first time I've ever installed a non-factory stereo by myself.) I would definitely buy from Crutchfield again (actually, I did, I bought a unit for my DD Mazda pickup from them and installation was similarly just as easy.)
Crutchfield customer service is great, definitely worth it.
