This item is a great, inexpensive way to upgrade your Camry and make it feel breand new again.
I did a lot of research before deciding to buy this particular unit. The cost of a Toyota OEM model ($2500) made no sense to me. The cost of a branded aftermarket unit, with installation ($1500+) was also prohibitive. I am 31, married, with children and have not much use for a super high performance sound system. I then found this unit and compared it to many others found on ebay and selling for $300+.
This unit, and those on ebay, are all made in China, and there's not a ton of information available from the manufacturers. They seem fairly similar in options. I ultimately chose this unit over the ebay units because the seller is from the U.S. and they responded very quickly to a couple pre-purchase email inquiries (by quickly, I mean within 10 minutes!). That gave me a certain level of comfort buying an unbranded product. I also bought a squaretrade 3-year warranty for around $30 for added piece of mind.
I received the item on schedule and it took me about 30 minutes (with absolutely no previous experience and a little help from a youtube video) to install. The wiring harness is totally plug-and-play. I've yet to get the steering wheel controls to work with the unit, and my next venture is to install the backup camera. I've used this now for a few weeks and have to say it was well worth it. Unit comes without an instruction manual on how to use all the functions, so it's trial and error - which is actually sort of fun. For $299, I give the unit 5 stars.
