07 Suburban w/Bose w/o Nav, Pioneer MVH-2300NEX

Post by ght » Tue Mar 13, 2018 4:53 pm

So, I'm about ready to pull the trigger on a DIY install, but after doing a few hours of research, I'm left with a few questions.

2007 Chevy Suburban Z71, w/ Bose, w/o Navigation
Pioneer MVH-2300NEX, iDatalink Maestro ADS-MRR, iDatalink ADS HRN-RR-GM5+

Should I be using the high level outputs or low level (RCA) outputs from the Pioneer to the GM5+ harness?

Do I plug the subwoofer RCA from the GM5+ to the SWR or the SWL out on the Pioneer?

Any idea if my truck has a center channel? How would I be able to tell if it did? (I don't see any obvious speaker in the center of the dash, just the two Bose speakers in the A pillars.)

If it does have a center channel, which RCA output on the Pioneer would that plug into?

What sound is passed from Maestro to the head unit via the AUX audio cable? I'd like to use that input to run a 3.5mm aux to the dash if it won't cost me any functionality. (The only AUX input in my vehicle is a 3.5mm jack that is part of the factory head unit and will be gone.)

Any recommendations on best way to tap into the OBD2 wires?

Does the speaker on the GM5+ need to be exposed or can it be installed under the dash? What sounds is it used for? Just warning chimes?

1) I recommend using the level matching circuits we provide in the GM5+
2) Yes subwoofer rca's go to SWL and SWR RCA outputs on the Pioneer
3) Center channel would be under the dash pad panel in the center of the dash. Turn on radio and stick your ear up on the dash and listen for audio. If you dont hear anything you dont have a center channel speaker and if you hear audio you have one. I usually leave it disconnect and place my SP1 speaker up there, but you can use the right front rca output from the pioneer if you want to use it.
4) ONstar and OEM Sat Radio. Once we use the maestro with Pioneer the AUX input on the Pioneer becomes a dedicated input for Maestro only. Cant use it for any other source.
5) We recommend that you use the provided connector for the OBD2
6)See #3 for location. warning chimes, etc come out of the SP1

Thanks for taking the time to answer all my questions. A couple follow-up questions, as the iDatalink instructions I find on the website seem a little different:

1) Any reason you recommend this? I'm just curious as to and advantages of one over the other. The instructions online seem to say that factory amps should use the low level RCA outputs, but I've seen others online say they used the speaker-level outputs.

2) It looks like there is only one subwoofer RCA connection from the GM5+, at least from the pictures I see online. If so, should this plug into the SWR or SWL? Does it matter?

3) Just found a picture of what the dash looks like if there is a center channel. I definitely don't have any mesh grille in the top of my dash, so pretty sure no center channel.

5) Didn't realize there was a special OBD2 connector. That's handy. The instructions say to connect to the twisted wires behind the OBD2 connector.

- when using the level matching circuits you're less likely to have engine noise.
- correct there is just one subwoofer RCA from the GM5+, doesnt matter which one on the radio you use

I have a problem. Took the stock radio out and I do not have a brown sub/center/backup cam harmess. The stock radio only had two spots for connectors, which seem to match the two plugs in the factory harness. So, had I wired up my GM5+ harness for the level matching connections. My speaker panels do say Bose, and I know there’s a sub under my center console. Will this setup work for me? Will the factory amp just pass the bass to the sub on its own?

Yes- not all trims of bose have that connector, so it's no cause for concern. In the trims where that connector isn't present, the signal is sent through other channels, and the amp uses its crossovers to generate the sub's output.
