There was a problem filtering reviews right now. Please try again later.
At first I didn't think it would work because I could get two different units to power up and all functions seemed to work but I had a problem getting sound out of any speakers. At first I thought maybe I had blown the internal amp of the new stereo but when the older one worked exactly the same (no sound), I thought that I couldn't possibly have blown the internal amps of both units, could I? so after re-reading the wiring instructions and making sure everything was connected proberly, I began paying attention the blue/white wire that I kept reading that was supposed to be an "amp turn on" wire. I had no clue what that was supposed to be until I read the blue caution tag that was on the blue wire of my older stereo that not only mentioned it could be connected for an auto antenna signal but for and amp signal...etc. Hmmm... So, I connected that blue wire to the blue/white wires of the harness and tried connecting everything in the car. Wallah! I now have sound!! Who would've thought. So, I took the brand new stereo and connected it's blue wire the same as I did the old one....again, Wallah! Sound!
I have to admit that I gave this unit 4 starts because in the instructions it mentions these blue/white wires to be amp turn on wires and not auto antenna wires. I think they need to update the instructions and do a bit more research on how different stereo manufacturers use their terms to explain the unit's functions and wires. Also, I am not pleased, as others have mentioned, about the creation of the tones used for the "GM tones". They ARE very loud and short. The original tone was more laid back and sounded as if it were such as a tubular bell being struck and not so peircing to the ear. These sounds out of this unit are just three very loud and fast bursts of tone which will take some getting used to. I know a person can adjust for the loudness but it doesn't make them any more pleasing.
The next and final reason for the 4 star rating is because I think it's an awkward idea to just have a person tap the brown wire to ground in order to get the Onstar level louder or softer. Why didn't the makers of this unit simply put a push button on the unit and label it the Onstar volume button so one could just simply push it momentarily to adjust the volume? Currently I am not signed on for the Onstar service anyway so I guess if I get in a crash I'm out of luck by them.
I have yet to fully install the new stereo in my dash because I have spent all this time and money making sure it was going to work first before I either install it or put the original stereo back in and forget a new one in this vehicle for now. I hope I can get everything to fit in such a cramped space with stereo, wires, and new oversized box. It is much larger than I expected.
All in all I think this company is on the right track and I hope the newer units are better and they have fixed some of these issues that I have read other reviewers have also complained about. I just can't afford to pay the prices for these units at this time.
One final question, does anyone know if these units have issues with being battery drainers? Seems I read that by a reviewer some where. Any comments would be great.
You must connect BOTH red wires on the harness to your red wire on your head unit.The instructions don't mention there being 2 red wires, which is dumb, but I found a lot of people having that problem.
Also, there will be A LOT of extra wires. Since this is generic for a lot of different manufacturers and models not all wires will be used. In my case I had 9 wires left over. I just taped them up with some electrical tape just to make sure no wires got loose or touched metal or anything.
Product is great, but they really need to work on those instructions
