Question: Don't know much about cars, do I need to buy something else to fit or install this into a 99 honda accord sedan?
Document: I still have the factory Infinity speakers and I love the sound so have not found any reason to adjust them.Only problem I have is more with the model of my car. I have a 2006 Hyundai Azera. The install kit that is needed leaves the deck at a bit of an angle instead of flush. This along with the volume control/iPod joy-stick sticking out, causes a little issue getting the iPod in and out if you need to. Otherwise, I think the deck is awesome if you don't use CD's anymore (and I don't know too many people that do).
I'm tempted to buy this unit for my truck and everyone that has seen it thus far wants one as well.Besides functionality (which is one of the easiest) it's aesthetically pleasing as well. The remote that comes with it is easy to use too and you can make your phone call with it. The display unit even has caller ID ontop of all the grace note data! Awesome!To conclude this review, I will say, that as a professional auto technician at a New car dealership, I sometimes have to install Bluetooth modules, and iPod kits into cars that are both difficult to use, but are buggy as hell.
I've had this radio for about 3 weeks now and its pretty freakin awsome! BUT!!! There is one flaw that I think sony should adress or update. The connections for the xm satellite radio are out of date. In order to get xm, you need to buy two pieces of equipment that are no longer made by xm. One would be the compatible tuner, and the second would be the translator. Each piece is around $110 and if your like me, you already spent $100 for the equipment to install it.
the clip on or permanant mic works great. I had pulled out and earlier version of a sony cd usb deck and the power and speaker port connector was the exact same so i had a clean easy install, within minutes, routing the small speaker line was about 2 minutes.. oh yeah, that and the internal ipod tray for my ipod cassic works perfectly as well, even while my phone was hooked up blutooth. the whole ipod menu was availiable when i clicked on the source button. I dont know if you can tell but this was a great buy, and i am now up to date in technology and loving it.
Overall, I have to say that it is good. Sound quality is on par for the price range. However I only use USB media. Never tried IPOD or anything else. Bluetooth sounds good. The reason for the 3 star rating and not 5 is because of a few key problems I noticed so far. First off is the size of the unit. Installation was slightly more challenging than other head units I've used in the past. It is wider and taller than a standard din sized unit. I had to cut out the mount kit with a dremmel to fit the housing into the slot.
I had 2 to choose from, this and Pioneer MVH-P8200BT. I picked this because it was $30-35 bucks less ($150) and it has features I need: hidden USB slot (better then Pioneer's hidden SD-card slot, USB is more universal), Bluetooth Audio Streaming (Bluetooth controls also seem to work), and good sound quality (I personally haven't heard other units, but it sure is better then stock HU due to better AMP, better DAC,  and equalizers). Pioneer unit on the other hand looks better, has color 3'' LCD, and has fully customization display and buttons color and dimmer to fit your car.
On this unit you can not display the time of a track with time remaining, you can only display how much time has currently passed on the track. It's a minor annoyance, but something I enjoyed on my previous stereo.The knob can be a bit difficult to press in without inadvertently pressing left or right, and I found that the best way to solve this was to do a three finger grab of the knob and push in.I use a classic iPod for my car stereo and have no problems whatsoever.
I purchased this radio after ready numerous reviews on this radio and other brand radios. I decided to go with this one as the bluetooth microphone was built in and the ipod stores inside the radio (out of the way). I could not be happier!! !My factory installed radio was suppose to be "premium", but something was missing. I had bought an Alpine for my daughter's car and it was way to hard to figure out how to use it and reading the manual was impossible. So after doing much review, I went with the Sony for reasons stated above.It does so much more than that.
And that's exactly what this is. Nice, clean, slick, and just plain awesome. Within minutes of fiddling with the system and figuring out how to access any of my 60 GB worth of songs, I was completely sold on the idea of just using my ipod instead of dealing with CD's. This will revolutionize my driving experience!The sound quality is fantastic, way better than my stock system (2003 Honda Pilot), and all the features and customization available make this a really good choice. The remote is nice, although I can't tell yet how much I'll be using it rather than just reaching for the unit.
Time will tell I suppose. It's nice to have as many buttons as it has though.Bluetooth hookup was as simple as could be with my Droid X. Within seconds I had my phone making and receiving calls as soon as i stepped in and started the car.I can't say enough good things about this unit. I don't know how to install car stereos, but I helped my friend do it, and after watching/helping him, I'm certain that this is very simple for anyone who has even the slightest bit of car stereo knowledge (be sure to get a wiring harness though!
Answer: You'll need something like this: Scosche Dash Kit for 1998-Up Honda Accord Kit
