I just bought my car 3 weeks ago and been searching around for an OEM like navi.. I've read about Rosen/flyaudio and other chinese HU..it seems like they all have their ups&downs, then I stumbled upon ottonavi site and I was able to get my hands on this ottonavi oem HU way lower than the selling price which is $699 so I took the deal, I know its another chinese HU and already know what to expect.. It came with practically everything you need without paying extra like (jbl harness, ipod cable, camera harness, 2 usb output etc) this might be the cheapest out of all the oem like HU.. it took me 30 min to install everything w/o any experience.. I've only own this for a day so heres my initial review.. fitment was 99% top left didn't sit as flush as I would like but non noticeable as u can see from the picture im just picky like that..but im sure it can be adjusted.. GPS, main reason I bought it, I mounted the gps antenna on the right side of the unit, and I get full bars..I believe it uses IGO maps, but can be upgraded..10 seconds to initiliaze, the voice is very low like its coming from the HU itself, but doesn't bother me as I will be turning it off anyways cuz I don't like the interruptions while im listening to the radio.. speed (mph) is -1 from the dash so its pretty accurate.. Radio works great boots up as soon as the car turns on then gps will initialize although reception could be better but doesn't bother me, btw sounds better too.. a friend told me who's an installer to move the gps antenna away from the unit and it might help with the interference... bluetooth works great, Im using an Iphone 4 and have no problems. DVD works great along with the remote included.. just ground the pink wire and your set.. backlight on the buttons at night doesn't get that bright it seems like its set near the lowest setting.. this doesn't bother me because I keep the setting at lowest setting anyways.. Steering wheel controls works fine without a hiccup also.. I will be installing a back-up camera and maybe hook up an Ipod in the future.. until then hope this review helps to those people looking for an OEM like HU.. update1: auxillary port still works.. Also, I was able to stream pandora and transmit the sound from netflix from my iphone4 using BT (a2dp).. When setting the time make sure you do the setting for the gps also.. update2: I connected an Ipod touch and it works fine.. On the manual it says the brightness will adjust according to day/night mode, but I can't figure out how to set it.. It seems like the only way to doit is to press tune/osd button and you can toggle to brightness as well as bass, treble etc.. Also once you turn off the car or dead silent you will hear a whine coming from the unit, but its just built in fan located on the back cooling the unit. update3: added a ccd camera from ebay..(camry 09) works great.. attachments: reverse cam, night buttons, jbl harness, ccd camera,testing usb..
