First review of anything ever so go easy on me.
I have had the pioneer avh-p4400bh in my 2001 jetta for about 3 weeks now and i love it. It is very user friendly and it works with my droid phone! I had the avh-p3300bt for about a week before i got this one and the difference is amazing. It does everything the avh-p4300dvd does and it comes with hd radio and bluetooth. Hd radio doesnt sound any different than regular radio, but the added bluetooth feature is awesome. I no longer search for a cord to plug in just jump in the car and hit play on my phone. I dont use apple stuff so i dont know how well it plays with ipods but im sure it great just like the 4300 was.

For HD radio, make sure that it's showing "Blending D/A" audio and not just "Blending Analog". On a few talk radio stations (i.e. - ESPN), i notice an echo when it's in Blending D/A mode but when switched to analog it's fine (and sounds like just regular radio as you note above).
