I purchased this to replace my older Pioneer and the added features are well worth the cost. Built in bluetooth is very nice. This unit plays all the types of files I have thrown at it. Windows Media, Mp3 and so on. The HD radio is also a huge plus.
I have XM radio and this unit shows the full title of songs. It has features I did not know existed while playing XM songs.

I received this DVD receiver six months ago and it has worked well until last month when the Bluetooth module became defective. While awaiting repair, I installed a Pioneer AVH-X5500BHS which has a nicer display in that it can be adjustably dimmed separately for both day and night use. Both receivers have equally good audio without an amplifier, if quality speakers are used. I'm waiting for the AVH-P4400BH to be repaired, but I sure do like the AVH-X5500BHS.

Definitely worth buying! Will improve vehicle overall and you'll love it

Pioneer AVH-P4400BH in 2002 Ford Escape
Pros:
Connects automatically to iphone 5/4s
Bluetooth calls are clear from both ends
Fully adjustable colors
DVD playback is sharp. I did hook up the brake switch properly because I'm a good boy and knew I'd be distracted otherwise.
Radio reception and audio are improved from stock radio
Touchscreen is responsive
Menus are logical and smooth

Cons:
iphone 5 doesn't seem to have full compatibility with app mode
Tuning the radio manually can be tricky while driving (set those presets)

I got this from this site on black friday. I will have to say that this is one of the best unit I gotten. It is nice user inteface and the bluetooth is a BIG plus. Phone comes in really clear unlike some other units i seen on the market.
Very fast delivery and it came with the wire harness for free. Great buy especially for the deal that I got it for on black friday

My only gripe is that the unit itself doesnt have a built in mic. You MUST plug the corded mic into the back of the unit and route it somewhere appropriate in the car or else your callers won't be able to hear you.

All other bluetooth units I've looked at have had both a peripheral mic built into the frame of the unit as well as a built in mic.

I have had plenty of other units like this but Pioneer did a good job of keeping what works and simplifying everything else. The touch screen is really fast. The EQ is great for fine tuning. Bluetooth and HD radio are worth the money. Picture is very clean. Remote comes in handy. Just tons of features. I love to watch DVD's on here. And its really easy to wire a relay to bypass the parking brake. Not to smart to have a movie playing while driving lol.

I have had it in my 2005 Camry for 6 months and this one is gonna stay. I run 2 Alpine Type R SWR-12DA powered by a Crescendo BC2000D (amp out plays my Rockford 2500bdCP)at a 1 ohm load. Alpine SPX-17pro (front doors) Alpine SPR-69 (rear deck) powered by a Alpine PDX-F4. All powered by a 270 amp alternator with a Kinetik 1800hc power cell under the hood and in the trunk. And by far this was the best product in my car. Just go get it. My only complaint is that I should've waited for the AVH-P8400BH to get in stock.

Ive had this unit for about 6 months now it works amazing the preamp outputs work amazing. I paired this unit with the a series pioneer speakers and buddy let me be the first to tell you that im thinking hooking an amp to the door speakers may not be good for my health as its already super loud. I also used a preamp output to feed my subs its a 4 volt output so the subs (2 rockford d412) sound amazingly clear and powerful. The layout of the unit is top quality and easy to work with as is tge 7 band eq which made all the difference and making the door speakers keep up with the 1200 watts pushing my subwoofers. I could go on but ill just leave you with this buy this deck u wont be disappointed. Make sure u catch a good ground when installing for better signal and clarity.
