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
