I'm trying to figure out which CANBUS decoder box will work with these 11bit GMLAN systems.

Can anyone tell me which CANBUS decoder box
- Edited
These are pretty old so it won't be any kind of advanced canbus. Like for me, I have a 2010 Silverado 1500 and I use GM-SS-05 that was shipped with the head unit and built into the harness. I have the open door display and chimes (needs external speaker also that was included). It also knows when I go into reverse as the camera lines are shown but i don't have a camera. The screen dims as well when the headlights come on. Nothing else. More models here for GM.
Can anyone tell me if my car is responding in these logs?

RAISE CANBUS box, original screen is color, try RZ-GM-11, original screen is black and white, try RZ-GM-01 again.
Hiworld CANBUS box, try GMF6 model.
Teklock Not true, it has both high speed, for the modules that are related to driveability (transmission, fuel pump control etc.) and low speed for the less important things like radio. I believe any canbus box for the head unit will most likely work on low speed but then again if they want to see driveability data like the new cars can, it could be both. Only the engineers / sellers of those things will know for sure.
I believe your truck has the 29bit GMLAN where my car has the 11bit. It has nothing to do with the speed. My car has three buses. A high, med, and single wire low speed which is what is connected to the OEM HU. I have 3 canbus boxes. The GM-SS-05 from simple like yours, the RZ-GM09 from raise and DJ-GM-01 from Dogen Electronics. None of these do anything with my car. For my info, check out the service manual for your truck and it will tell you about the buses and which one is connected to what. https://charm.li/Chevrolet/2010/Silverado%201500%202WD%20V8-5.3L/
This is for my car and 2010 Cobalt:
"The communication among control modules is performed through the GMLAN high speed serial data circuit and the GMLAN low speed serial data circuit. The modules that need real time communication are attached to the high speed GMLAN network. The body control module (BCM) is the gateway between the networks. The purpose of the gateway is to translate serial data messages between the GMLAN high speed buss and the GMLAN low speed buss. The gateway will interact with each network according to that network's transmission protocol. Refer to Body Control System Description and Operation (Description and Operation) for more information about the gateway.
The powertrain control module (PCM) on this vehicle, uses a class 2 serial data buss. The class 2 buss is only used for diagnostics and the service programming system (SPS). During normal vehicle operations, there is no communications over the class 2 serial data buss. Normal vehicle operational messaging for the PCM is sent over the PCMs GMLAN high speed serial data buss.
GMLAN High Speed Circuit Description
The data link connector (DLC) allows a scan tool to communicate with the high speed GMLAN serial data circuit. The serial data is transmitted on 2 twisted wires that allow speed up to 500 Kb/s. The twisted pair is terminated with two 120 ohms resistors, one is internal to the powertrain control module (PCM) or engine control module (ECM) depending on regular production option (RPO) and the other is internal to the body control module (BCM). The BCM is considered the DLC termination point of the link and the engine management controller is the other end of the link. The resistors are used to reduce noise on the High Speed GMLAN buss during normal vehicle operation. The high speed GMLAN is a differential bus. The high speed GMLAN serial data bus (+) and high speed GMLAN serial data (-) are driven to opposite extremes from a rest or idle level. The idle level, which is approximately 2.5 volts, is considered recessive transmitted data and is interpreted as a logic 1. Driving the lines to their extremes, adds one volt to the high speed GMLAN serial data bus (+) and subtracts one volt from the high speed GMLAN serial data bus (-) wire. This dominant state is interpreted as a logic 0. GMLAN network management supports selective start up and is based on virtual networks. A virtual network is a collection of signals started in response to a vehicle event. The starting of a virtual network signifies that a particular aspect of the vehicles functionality has been requested. A virtual network is supported by virtual devices, which represents a collection of signals owned by a single physical device. So, any physical device can have one or more virtual devices. The signal supervision is the process of determining whether an expected signal is being received or not. Failsofting is the ability to substitute a signal with a default value or a default algorithm, in the absence of a valid signal. Some messages are also interpreted as a heartbeat of a virtual device. If such a signal is lost, the application will set a no communication code against the respective virtual device. This code is mapped on the Tech 2 screen as a code against the physical device.
GMLAN Low Speed Circuit Description
The data link connector (DLC) allows a scan tool to communicate with the low speed GMLAN serial data circuit. The serial data is transmitted over a single wire to the appropriate control modules. The transmission speed for GMLAN low speed is up to 83.33 Kb/s. Under normal vehicle operating conditions, the speed of the buss is 33.33 Kb/s. This protocol produces a simple pules train sent out over the GMLAN low speed serial data bus. When a module pulls the buss high, 5 volts, this creates a dominant logic state or 0 on the buss. When the buss is pulled low 0 volts, it is translated as a recessive logic state or 1. To wake the control modules connected to the GMLAN low speed serial data buss, a high voltage wake up pulse is sent out over the buss, the voltage level of the pules is +10 volts. Modules connected to the GMLAN low speed buss can be part of a virtual network as described in the previous paragraph. The modules on the GMLAN low speed serial data buss are connected to the buss in a parallel configuration.
Class 2 Circuit Description
The data link connector (DLC) allows a scan tool to communicate with the class 2 serial data circuit. Class 2 serial data is transmitted on a single wire at an average of 10.4 Kbps. The bus is active at 7 volts nominal and inactive at ground potential. When the ignition switch is in RUN, and a scan tool is connected to the DLC, the powertrain control module (PCM) will start communicating diagnostic information over the class 2 serial data circuit.
Data Link Connector (DLC)
The data link connector (DLC) is a standardized 16-cavity connector. Connector design and location is dictated by an industry wide standard, and is required to provide the following:
* Pin 1 GMLAN low speed communications terminal
* Pin 2 Class 2 signal terminal
* Pin 4 Scan tool power ground terminal
* Pin 5 Common signal ground terminal
* Pin 6 High speed GMLAN serial data bus (+) terminal
* Pin 14 High speed GMLAN serial data bus (-) terminal
* Pin 16 Scan tool power, battery positive voltage terminal"I've done lots of research and this is very much true.
