Review
I've had this player installed for around 1 and a half years, and so far it hasn't failed me at all.

It is very easy to use and has a pleasing interface that can be customised to your own preferences (Background, colour of the buttons at the bottom etc.)

Also, the sound quality improved dramatically as compared to the stock headunit.

What I like
-Easy to use
-Improved sound quality
-Customisation of interfaces/buttons

What I do not like
-Nothing much!

I installed this on
Honda Airwave

Review
I did not purchased this player. It comes with the used vehicle which I believe it's installed by the previous owner.

Overall it has most of the required features, including bluetooth for phonecalls etc.
Personally I feel it may be slight laggy at times but it is still acceptable. Only feature which i wish to have but it doesn't, is the capability to play FLV files.

What I like
Design
Bluetooth
7" LCD

What I do not like
Sometimes laggy
Not able to play FLV files.

Review
I installed the AVH-X5550 around 1 year ago, due to the fact that I wanted to add navigation and a reverse camera to my Bravo. So far, I have not been disappointed. Immediately after installation, I felt that the speakers sounded better and much more "alive" compared to the stock headunit.

The user interface is also very easy to use, and the familiarization process is fairly short.

All in all, I would recommend this head unit to anyone who wants a good all-in-one unit.

What I like
-Visual Equaliser
-High quality display
-CD changer and SD card slot behind the screen (pops out)
-Customisable colour options for buttons

What I do not like
-Can be considered a bit pricy...
