New HU needed Bluetooth, HD Radio, USB FRONT and/or Rear, SDHC if available

Wow, that is pretty price IMO for a Dual. I've never owned a Dual, but they seem like cheap Taiwan stuff to me.
For few bucks more, you can get a quality name brand HU that will be more reliable, more sturdy and sound better. Its your budget, but I would only buy name brand even if I had to give up a feature.

If you could live without the BT built in, here are a couple that I'm sure are built much better:

I'm not a huge fan of Sony HUs, but they are better than the cheapo companies. (Boss, Dual, Craig)

In 25 years of car radios I've owned I've never had a Pioneer let me down.

IMO HD radio isn't worth the expense and not all markets have HD. I live outside philly and I only know of three major stations that have HD broadcasts.

All the above info is just my two cents

 

You could get a Sony MEX-BT2800 with the optional HD tuner accessory for about $189, but it has no USB.
