2015 GMC Acadia JVC KW-M845BW Install

Post by leecox » Thu Jul 12, 2018 5:53 pm

I have a couple of general questions and have looked through a few of the other forum posts related to my vehicle type.

2015 GMC Acadia SLT2
Bose Intellilink System
Navigation/SiriusXM/Bluetooth/Rear Audio Controls

I have purchased a JVC KW-M845BW to install along with the Maestro RR and GM5+ T-Harness. Primary use is Apple Carplay/Android Auto.

I've read that there may be issues with the RCA outputs line level and I might need to wire into the radio amplifier outputs. Can you confirm that? I'd like to use the RCAs with the Bose Amp if possible.

I have the hands free calling options with the Factory headunit. I have the extra mic that came with the JVC kit. Do I need to use the JVC Mic (with the intention that I'll be using Apple Carplay and Andriod Auto)? Will the factory Mic still work with hands free calling outside of the phone casting solutions?

There is a blue Frakas cable that plugs into the factory radio, for I assume Nav function (given that the Sirius is retained with the factory headunit removed). Is there an adapter available to convert this for the JVC? NAV1 Adapter doesn't list it as compatible. I have the other adapters (USB/Radio Antenna), this one seems much harder to find. I'd like to avoid placing and running another Antenna.

I know these are pretty basic questions. I REALLY like the Maestro solution. Only issue I've found is the need to use Internet Explorer to program the RR, but it worked well and programmed successfully. Thanks so much for putting this together.

1- You can try the RCA's first since they are just simple plug-in's. However note that there is the possibility of engine noise or whine when using this method. We recommend on vehicles equipped with the Bose amplifiers to use the level matching circuits we provide.
2- If you are planning on using CarPlay or Android Auto you will need the JVC microphone. The OEM mic is retained for Onstar features.
3- If it is a Fakra plug then the NAV1 should work with the vehicle. If it doesn't the GPS antenna can be hidden under the plastic parts of the dash, it does not need to be visible. Just remember to not place it under metal.

Hi Justin,

Thanks for the reply and the info! I installed everything this afternoon. I did use the included NAV GPS antenna, Mic, and the level matching circuits. It's all working great. One question I have is on the Maestro unit when it starts up, what color should the LED be? I got 2-3 Red flashes. I checked all of the options and they all seem to be working. Just curious.

Additional feedback after extended use and programming. The programming for the factory Sirius XM module needs to be adjusted. Channels 5-9 aren't showing in the channel list. If you go into the channel list there are blank rows for them under pop. You can select the channel and save it to a preset, but not direct tune to the station. Not sure how many others are doing the same thing.

This is normal operation. You will get a couple red flashes when it first boots up because the Maestro is waiting for the radio to power on so they can talk to each other. once communication has been established the Maestro's LED will no longer flash

Thanks Justin!

These Notes from the Field aren't really issues, but I do feel they could be valuable for other consumers and the Datalink team for this specific configuration.

The unit does a fantastic job of retaining all of the needed functionality and makes the wiring with the GM5+ kit a breeze. I'm very appreciative of the time and effort put into the kit and programming. Really liked the ODB2 plug on the hardwired connections to help with placement. I haven't removed it yet, and I'm not sure that I will given how elegant it is. I really appreciate it.

The ACC-NAV1 does work the with 2015 GMC Acadia with the Intellilink headunit. It isn't listed as compatible, but works.

The biggest issue that I've had with the Maestro RR is something that the marketing team needs to be aware of, the inability to hear the vehicle Chimes when the unit is playing the factory SiriusXM tuner is disturbing. I get the technical reason why it doesn't work. I'm not really even complaining about the issue. Our car has lane departure warnings, pre-collision warnings, cross lane traffic warnings backing up. In short, it's making noise all the time. I wasn't aware prior to purchasing the unit that this limitation existed. I didn't know until I read it in this forum after my wife mentioned not hearing Turn Signal and other chimes/warning sounds when she got in it to drive the first time. We both agreed that it wasn't an acceptable condition for us. I installed an aftermarket SiriusXM Tuner for the headunit to resolve that pain point. I think there should be some notice in the description for the unit that to retain the Factory SiriusXM you will not hear other sounds. If I'd known that it very likely wouldn't have prevented my purchase, just saved a removal/install step. If there is a notice about this, I apologize for not already seeing it.

Another minor improvement would be for those cars equipped with the a GM heads up display (ours has it). The factory headunit passes the XM Channel ID (when changing stations) and Song Name (when a new one plays) to the HUD. I'm not sure that's something that can be replicated, or if Datalink is aware that is a factory capability.

Thanks again for providing this solution and making it available to us in this highly integrated age.

Lee, I had crutchfield do their ready harness as it was worth $25 to have them connect all of the wires. I have a 2016 Acadia with the same radio you did. They connected the high level speaker wires and told me they always did that with Bose amps and speakers. Mine sounds really good.
