I have a 2008 Pontiac G8 GT with the premium Blaupunkt stereo. I cannot remove this due to the HVAC controls being built in. I just bought the 500bt and the ND-G500 so I can hear the nav and Bluetooth through my car stereo speakers, which are going to be replaced with aftermarket speakers. I also have three other amps to run my car stereo, along with an Audiocontrol DQL-8 OEM integration unit, which utilizes high level speaker inputs. Will I be able to utilize the ND-G500 and the Audio Control Unit at the same time? I know the G500 utilizes the high level speaker inputs, but im not sure if I can then run them again to the Audiocontrol unit. Finding the answer has been quite frustrating...if you have car stereo install experience...please chime in!!! thanks

I am not sure I follow you on using the ND-500. If you are replacing basically the whole system, why do you want to backward integrate to your old system. I realize that you need to keep your factory radio for climate controls.

It seems to me that you would want to install your F500BT, speakers, and amplifiers and not utilize the factory radio (besides the climate controls). If you want to keep your door chime and beeps and all crap, you could just wire a small speaker to the left front output of your factory radio, hide it under the dash and call it done.

Perhaps I am off in my answer. Is there any more information you could give about what you are trying to do?

Sorry about the last reply...My mistake, I thought you were trying to put in a head unit (F700), not navi.

To answer your question, you should wire your F500 after your amplifiers. The only thing you have to make sure of is that the internal relays in the ND-G500 can handle higher inputs like that of aftermarket amplifiers (I have seen problems with the older Parrot stuff and amplifiers). With this wiring configuration, you will only be cutting (muting) one source of audio.

Your other option, if the Audiocontrol DQL-8 OEM integration unit has a mute input, is to connect the mute output of the ND-G500 to the mute input of the Audiocontrol. You need to connect a single speaker to an output (usually the left front) of the ND-G500, but would probably get much better results.

Hope it helps

I was actually thinking about your first response last night in bed...I am a noob when it comes to wiring and stuff, and sometimes the flow of a system boggles my mind for a minute. I had a brain fart when thinking the g500 amp was going to be connected to the speakers, when in actuality, the speakers will be controlled by my zapco amps. I think what i will do is this. the car has onstar, which utilizes a center channel speaker. I will never use onstar because it sucks, so i will take part of your idea and wire in the g500 amp to that center speaker only, setting up a mute connection for muting the rest of the speakers in the system. it should be powerful enough to handle the bluetooth and nav directions, then all the rest of the speakers are controlled by the amps and audiocontrol system. if i have missed a step or am off in my thinking...please let me know...i would be a good learning experience. thanks for the response!

Sounds like you have it all figured out. Let me know when you are done!

Happy installing

Your first comment fits right in. The ND-G500 takes speaker level input and mutes it as needed putting out speaker level radio or GPS audio as needed. Your amps using speaker level instead of line level makes it easy.

Good Luck!
