By the way, if anybody is interested in trying my idea above as an alternative to the NavTV unit, I can build and sell you the necessary harnesses to do this.Just email me at [email protected]

An alternative plan to the NavTV unit is to use a DSP that accepts signal from a tablet or phone.Use the tablet/phone to play your music and just use the Bose amp to play the factory chimes,beeps and radio through a speaker that you mount under the dash somewhere. You'd need to buy harnesses for the speaker outputs if you want to make it easy and just utilize the factory wiring that is already in place.You'll also need a harness that bypasses the Bose output audio signals and yet gives you that front left output to hook to the speaker that you'll mount under the dash.

Stock sub is not connected to any of those harnesses in the picture.Did you pull those out of the Bose amp? If so they are just signal or data wires. .

Exploid,no it doesn't. There are 4 different types of non-Bose systems and they are all self amplified. On another note, I have read a lot of posts on here about this NavTv unit for the Bose systems and I must say that for the money people pay for these(in the $600 range) the performance seems very poor. That is disappointing because I was thinking that was definitely the way to go as far as upgrading an entire system in a truck with the factory Bose. Seemed way better than getting post amp signals. I think maybe that company should have thoroughly tested the unit before releasing it to the public.

You can split the subwoofer signal and use both inputs on the LC2i. The rear doors are the worst place to get signal from in these trucks(and most GM's for that matter).It's not full range I guarantee that.Probably bandpassed from like 150hz to 2000hz. I'd like to get into one of these and go through the outputs with a DMM and test tones just to see how Bose sets up the processing in that amp.

Unless the GM schematics I have are wrong the 2019's and up do not have ANC. For some reason, GM stopped equipping the trucks with that feature. I know because I build audio wiring harnesses for these trucks and have all the schematics from 2007-2020. The X3 connector at the Bose amp contained all the microphone wires and on these newer ones there is only 1 wire going into it for data transfer.

The audio common is the inverted signal on a balanced input.Unlike unbalanced inputs where there is basically a shield and a signal, a balanced input has a hot signal and also an inverted signal that is completely out of phase with the hot signal. The inverted signal is also known as the audio common.

If you take that to a dealer to have the problem fixed be sure to pull all of your audio gear and cover up those wire splices as good as you can because you have voided the electrical warranty and possibly the entire vehicle warranty by splicing into the wiring.

Not only are people hesitant but even Crutchfield recommends not replacing the factory head unit in many vehicles now.Aftermarket HU's are going to be a thing of the past soon unless these companies like Pioneer,Kenwood,etc start figuring out how to integrate into factory systems.Problem is that the technology is so complex and therefore too expensive to make it available to the average consumer.

Both the AmpPro and NavTV Zen units act as virtual replacements of the stock Bose amplifier. Neither of the units use the "post amp" Bose signal but rather they use the actual CanBus(MOST serial data) signals that come from the stock source unit. The modules convert the data signals into analog full range line level RCA signals usable for most aftermarket amplifiers. I was curious about that myself so I did some research and looked at some random late model Sierra diagrams in my database.I checked the connectors that the AmpPro uses at the stock source unit.It uses 2 of the connectors at the SU,both of which contain the MOST serial data and the other important low speed GMLAN data signals.The question is which module has higher quality inner components and reliability between the AmpPro and Zen units?

I would like to thank you guys on this thread that have given me good reviews(I'm John-1pocket). I'm very humbled by your comments and am extremely grateful that you've given me a chance to help you out. My preferred contact email is [email protected] but if you are having issues with that address then try [email protected] I know in the past you've read some guys say they've received their order very quickly and sometimes that was the case.However,in recent months my business has really grown and I'm typically not able to deliver so quickly.I don't scratch people's ears,I tell them the truth as I work a full time job(50+ hours a week) and do this harness business on the side so sometimes things can get a bit backed up.But know this,when you order a harness from me you will always get an honest lead time. Feel free to ask me any questions here and I'll do my best to answer so that it may benefit the whole group.

The Fix86 is certainly a fine choice but by no means a "must" for Non-Bose systems.Many have ran their stock speaker signals straight into the speaker level inputs of a 4ch amplifier and used the RCA passthrough to feed signal to their mono bass amp yielding fantastic results.

That NavTV unit is only going to work on a factory Bose system.It replaces the stock amp basically.The I0R base system has completely different connectors and wiring configurations.

You could send the Ethernet bus signals and low speed gmlan data circuit into a Bose amplifiers X4 connector on the proper pin locations but the issue is that the Bose amp doesn't have the circuitry for radio controls like volume up/down....power on/off etc. I just don't see how you could get that to work,I wouldn't even try it.You're better off just upgrading what you have with aftermarket gear.

That harness will work in your truck then.
