Summary: Bought this unit but did not open the box until 9 months later. Installed no problem and worked well with Sirius as well as the latest map update (took quite a long time to install)... Note that the bluetooth add-on worked great with iphone 3GS but while recognized in iphone 4 and stereo mutes with call, no audio or mic pickup... useless.... But all of a sudden, the screen just displays the Clarion logo and does not change to display controls.
Summary: Alright, Ive had the headunit for nearly a year now, and am ready to pass judgment upon it. Pros: Reads my ipod touch and 5th gen ipod, and works well with both. The DVD player is awesome, no problems there. The motor in the screen has always worked well. Sound quality is acceptable. Cons: The GPS unit is an epic fail. If you have a LOT of content on your ipod, it takes forever to find what you want.
Summary: Overall, a very functional and relatively easy to install unit. I don't use the DVD or backup camera, but everything else that I have tried works great. iPod functionality is good. The Navigation functions are adequate, not every feature I'd like is there (big picture map on demand, for instance) but otherwise works well. The integration of phone, navigation, etc. is great. Pauses iPod or radio during a phone call using an iPhone as the iPod.
Summary: I got this system to replace my 6 disc Bose unit in my Nissan that broke. I had it installed by a professional shop and they did a good job as far as the install goes. However the unit is underpowered compared to my Bose system (as was expected). The Nav seems to be ok, the voices that are available are pretty hard to understand as well as sounding like an old answering machine.
Summary: I've had this unit for about 2 months now and I have to say I'm not as happy with it as I hoped I would be. This unit was listed as the only model that could provide GPS in a single DIN size, which is why I purchased it. The other selling feature for me is that it supports the steering wheel controls. I did have some trouble getting everything working correctly, but that did get worked out. The GPS, on the other hand, leaves quite a bit to be desired IMO.
Summary: Very nice package unit, navigation, usb drive, dvd unit for the price. For value it is excellent. Nice large display, easy navigation between audio and nav screen. GPs antenna works well through windsheild on dash. USB gives adequate folder info. I have not tried the satellite radio function. Text to speech sucks. Sounds like an old voice box from the 70's embarassing and terrible audio. If text to speech is not on, the voice direction audio is fine.
Summary: The good; Sharp video, easy install and works very well with the additional Sirius radio. Does all that it says it will do. Easy to bypass the DVD park thing. Seems to be reliable. GPS antenna very sensitive even when located under large rear window. The bad: Just doesn't do it real well. Except the Sirius. GPS has neat features, but will take you on some really odd routes. Try it on some familiar routes to see how it thinks.
Summary: I just received the NZ409 and elected to have it professionally installed instead of doing this myself. Everything I've read online said that the 2003 Honda Civic is pretty "tight" and it may not be easy to do this as an amateur. In addition to the head unit, I also had a backup camera, Sirius SC-C1 Satellite Radio and Blue Tooth installed. The good news: The Clarion's menus are pretty intuitive and easy to navigate through the different levels.
Summary: Pro: the price was right with the nav and it is well integrated. The sound is right up there with the Alpine I had before. It does run my iPod Nano as advertised. When I played a DVD, it played the music but not the video (because the parking brake was not on)...that was cool. Con: I tried as hard as I possibly could to find a DVD player that would let me search through the iPod titles..
