Adding an aftermarket radio to 07-14 FAQ

wait, so the maestro GM5+ or the crutchfield iDatalink HRN-HRR-GM2 plugs into the radio and then the satellite XM receiver will get a satalite signal through that?​

it's an external XM tuner that plugs into the radio so hence the confusion.

Yes I connected the GM5+ to all open connectors (except the rear AV harness, never used before, don't plan on using now) and then in the Alpine radio settings I had to select factory XM tuner, and it's been working fine for a year. No extra harness connections or anything.

thanks

For wireless apple car play, i had to buy a separate adapter (GM GPS antenna to Pioneer) this was not included in the crutchfield package and quite annoying i had to wait for it. Some aftermarket head units now come with wireless apple car play and android auto, if your gmt900 came with factory gps then you already have the gps antenna in the sharkfin and you do not need to add the aftermarket head unit gps antenna and snake wires through the dash. this is not listed anywhere in my research hence the post.

Sup yall, wanted some advice on a harness for my SSV. The only options I see here are for models with bose/navi/TV/wheel controls/BU camera... I don't have ANY of that and would prefer a cheaper solution.
As I understand it, my biggest hurdle would be retaining the chimes and turn signals, but I may have a work around if I can find more information on how the operate and on what wire.
Thanks in advance.

I've been watching this thread for years, and still am waiting on a simple & affordable plug'n'play solution to upgrading the Bose w/Nav headunit. Everything sounds cobbled together so far.

Much of the cobbling involves supporting the rear entertainment and steering wheel controls. If those aren't important to you I suspect someone on this list can make some Much cheaper and less cobbled suggestions.

It's silly but i paid extra to support my rear entertainment and I've never even looked at it before or after.

With a Maestro RR you can install anything you want and still maintain all factory functionality. It is an added expense above the cost of the head unit but as the old saying goes, "Buy once, Cry once". In the grand scheme of things it really isn't that much extra expense to keep everything working.

It is funny, I just posted this and then when looking in the for sale section seen this...

I have no affiliation with the seller, just thought it was funny. Also a decent price in my opinion.

idatalink.com maestro ADS-MRR w/ harnesses for 2007 suburban

This has been sitting on the shelf since I sold my suburban. 100 bucks plus shipping? It is the ONLY kit that works perfectly with the Bose systems...and if you're here, you already know.

So, the Maestro RR is the only thing I'd need? Crutchfield's discription states that it'll lose multiple functions:

Installation notes:​

• In order to retain your vehicle's warning chimes, you must use a factory integration adapter recommended by Crutchfield. Failure to do so may result in serious injury and/or death. Crutchfield cannot offer technical support for an installation undertaken without this adapter.
• This harness will not work with any receiver/amplifier with an output higher than 25 watts RMS.
• This interface will not retain front-rear fader control in vehicles with RPO code Y91 (Premium Bose). You can find the RPO code on the service parts identification label in the glove compartment.
• This wiring interface works with non-amplified systems or any system in which you're not using the factory amp. The interface retains warning chimes and Retained Accessory Power, and provides a 12v accessory output. The interface does not retain OnStar or factory amplifiers.
• The wiring interface retains warning chimes, OnStar, rear seat entertainment, Bluetooth, and the factory amplifier.
• The iDatalink harness connects the ADS-MRR module to your vehicle. In most applications, you'll have to connect its OBDII connector plug to the OBDII diagnostic port under the driver's side dash. For more details, refer to the install guide you'll download from the ADS website when you flash the module.
• The wiring interface retains the steering wheel audio controls, rear seat control, the Bose amplifier, and warning chimes in your GM vehicle. The interface also provides connections for retained accessory power, vehicle speed sensor, illumination, reverse trigger, and parking brake. It does not retain OnStar.
• The wiring interface retains warning chimes, OnStar, Bluetooth, and the factory amplifier. You'll have to program it online.

Crutchfield's notes also contain multiple contradictions. So I'm not sure what to say.

I don't use Onstar so if I did lose it I wouldn't know.

It is funny because in one sentence it says you lose it and then in the next it says you retain it, same goes for the factory amp, one sentence say yes, the other says no. I know it works beautifully with my factory Bose "dumb" amplifier. I don't have the Y91 "Smart amp" so I can't speak to that.

The one listed on here for sale says it has the unit AND harnesses needed for the GMT900 trucks, so other than programming certain features, like which steering wheel buttons you want to control different functions, you shouldn't need anything else other than a different headunit.
