Review on Multimedia Receiver AboutBit Bluetooth Subwoofer by Jay Jeong

LONG REVIEW WARNING: The reason for such a long review is that I wanted to talk about some issues I was having that were not the fault of the device. This device is amazing for the price and I talk features throughout the review. I hope this helps someone else who may be having the same or similar issues. I like my new head unit. I had a very cheap 7" size 2 touchscreen (all I could afford at the time) in my 2004 Tahoe with a factory Bose system, but something happened and I lost all sound. Long story short, the person who installed a single din radio in it before I got it installed the wrong interface and rewired some pins to make that interface work instead of getting the right one. They installed a GMOS-01 when they needed a GMOS -04. I had my brother in law help me install another one with this old interface (which we had to modify on our own interface to make it work) and it worked Good for a year then the sound got worse and worse until I lost it completely. My first thought was that it was because there was a wrong interface and it had eventually died but couldn't afford the right one until recently. So the first thing I did was replace the interface with the right one, still no sound from the head unit I had. Oh sure my next hope was that it was just a main unit so I bought it. When I received this I thought at first I might have to return it because it was larger than the product photos (there are extra tubes around the radio itself as you can see in some photos from other reviewers) and it wouldn't fit in the room where I could put my radio, it was too high. Then I realized that the extra edge just pops out when it doesn't fit. It was a great relief! So I hooked everything up to the new interface, followed all the instructions and still only made a faint noise. After some research, this turned out not to be the main unit (I really didn't want to return this main unit until I found out why). We learned that the previous owner bypassed the factory Bose amp! After about 2 weeks trying to figure out why I finally have a nice good sounding radio with what I need. I don't think the sound quality is entirely the head unit's fault though, I do have engine whine, but I think it has to do with how the previous owner mixed up the wiring and I have yet to figure that out. I also like the steering wheel remote that comes with this unit. I have steering wheel controls in my Tahoe, but it costs another $50-$55 for another interface just for the steering wheel controls, so I just use the remote that came with it instead of buying another interface and it works. Excellent. It was just an added bonus to buying this device over others I've looked at. I have not yet used the camera that came with this unit as the camera I had from another main unit still works fine and I was able to connect it. precisely because it is the same type of camera. I was thinking of either installing this camera as a front camera (which is another benefit of this device, you can add a front camera too) or leave it as a backup if the other one fails. The touch sensitivity of this machine's screen is AMAZING! It's 100 times better than my old device. The only thing I haven't been able to figure out with this unit is that I still can't get the rear entertainment (DVD player) to play sound through the radio. I don't blame this unit for this, just needs more research because I believe it may have something to do with the previous owner's interface or rewiring. I thought I had it when we probed with a multimeter but it didn't work. So if you have a DVD player in the back seat and are trying to get the sound through a secondary device, that's not the only thing you need to get it working. Do your research to set it up properly and then buy this device. The only real complaint I have about this device is that the instructions could have been a bit better. Other than that I am very happy with my purchase and would definitely recommend this main unit to anyone on a budget.
