Great stereo

I have had mine for about 6 months now. So far it's been through a range of temperatures from 113F to 35F, plus enough humidity to actually turn paper soft like a rag. Stereo is very easy to use, looks great and is easy to see day or night, even in direct sunlight. Very simple installation. For the style and cost you can't beat it.

Love this site

SE made ordering and installing a breez. No questions if you had everything you needed to do it right the first time, like some electronic sites out there. Also you can't beat the price anywhere.
As far as the unit goes is it is everything you could want it put my xm and ipod connections in one clean unit. It is also easy enough for my wife to use everyday because it is in her car. there are definitely cooler units out there but this is it for this price

Nice unit without to much bling

I've been a Kenwood fan for a lot of years. Every Kenwood product I've owned has held up very well. My last head unit lasted 10 years and I have KW amps still pounded after 15 years of service.
I needed a 6 channel deck but I didn't want a bunch of bling I'd never use. This is a pretty straight forward deck to use with some nice usable features for a average person. A biggy for me is a rotory volume knob. The user's manual is a little weak, but that's standard for KW, but it's enough to get you going and with a little playing around, you'll be cruising through the controls like a master in no time.

Great value head unit

+ Kenwood name = quality head unit
+ Sound quality is unmatched in this price range
+ 3 sets of preouts (front/rear/sub)
+ 3-band parametric EQ for compensating your speakers' flaws
+ Optional accessories can be used to gain equal functionality of head units costing up to 4x as much as this one

- Somewhat limited in features compared to Kenwood's eXcelon line (no surprise there)
- Doesn't install itself...?

Bought this for a friend a while back and he absolutely loves it. The only complaint I have is that it doesn't come with the iPod to USB cable, but those can be bought pretty cheap almost anywhere. The sound quality is fantastic as is always to be expected from Kenwood. From what I can tell, this model only suffers slightly when compared to the sound quality of their eXcelon line (my favorite). The breadth of features provided here makes up for any of its shortcomings, though. If you desire, you can purchase any number of accessories and make this unit the near-equal of almost anything that does CDs only.

Simply put, this is, in my opinion, one of the absolute best head units for the money. I dare you to try and find a more feature-filled and all around better head unit for the same price.

After going through a JVC Kameleon (very nice i might add, til i accidentally ripped the face off off) and some dual stuff, i decided to go Kenwood everything in my truck and i bought this. i had some issues with some speaker wire touching together and the head unit wouldn't do anything but go into protect mode which is very nice because without it i would have fried the unit. But i fixed that and turned it on. i love it. it has really nice controls, and it looks sick!!! Kenwood everything from the amps subs door speakers and this. sounds perfect i love it

The pricing was the best and the service support team was over the top when i called with ?'s about models and speakers...

Great deck for the price

This deck is great if you are on a budget. Great looking deck, ipod hook up is a usb female end, that you use your White usb to ipod cabe plugs in to it, so that is cool. The Ipod controls are a little confusing till you figure it out.The only thing i can complain about, is that if you put the random on when in a playlist or album you can't go back to the menu without turning off the random. other than that it's a sweet deck. Good for only a 100 bucks or so.

very good deck

i was very impressed w/ this head unit. i was looking 2 get it at the competitor's site, but it was $50 more there. sonic sent me everything that i needed 4 the install. after i installed it, i was very impressed w/ the quality of the faceplate, and the features that it has. like the guy below me said it is a little difficult 2 get used 2 but once u do its no problem. i did a lot of research b4 getting this head unit and would recommend it 2 anyone b/c it does what it claims and is a very good product.
