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

January 22, 2010 a great stereo for the money!

this stereo is great for the $140 i got it for...only funny thing is that in order to change radio station with the right dial one would expect to twist the knob, but you have to press it right or left to do so...iPod connection is good bc it charges your iPod, but you no longer can control the iPod by the iPod itself which i would have loved...the EQ can be personalized to certain tastes, and this stereo did liven up my speakers compared to the stock unit on my 1990 toyota corolla so im lovin my new stereo...remote control use is straightforward, its always nice to know your stereo can be controlled by it ;),has not failed me and its 6 months old,working like new!
