Programming HMI module or multi media module on 2015 k3500
Customers radio doesn't work and had it checked at dealership. Was told it needs the HMI module(also listed as multimedia interface module). When i look up programming it, the repair info talks about copying the file to a usb drive and programming that way. I have never done one through a usb drive, is this just a standard usb stick and does it just get plugged into the multi media port in the center counsel. It says to plug it when key is on and entertainment system on and it will automatically update, just follow the setup instructions on the radio. The dealer had told the customer that they were the only ones able to program these.
Yes the USB goes in center console. Be aware these take a long time to do. Couple hours. Dealer is making an assumption of your abilities.
Good to know ahead of time, that takes that long to complete the process.
Any idea how big of usb stick i would need
NO. I think we use a 1 G. It says when you are doing it
GM recommends a 8gb usb
Hi David. There have been a couple of recommendations in the dealership environment for programming with a USB. 4-8GB was the standard for some time, but 8-16 GB is also identified, unless otherwise specified. At this time do not use a USB larger than 16 GB. If using too large a USB, the system may time out before the files are located on the drive, so an adequate size USB is better. Here is
Hi Sam. Rather than the "Dealer is full of it", the reality is that the dealer representative may be making an assumption, simply from a lack of awareness of the level and types of programming that are now available in the aftermarket. We all know what "ASSUME" means in regards to knowing for sure what other entities have available to offer as services. Dealerships generally only have
I agree that was inappropriate. I should have edited and didn't. I hear it every day from customers, Dealer said only they can do it, or dealer said a used one can't be done. I understand their approach. Apologies from Michigan
No worries Sam. No harm, no foul. When I worked in the independent field many years ago, there was much that I didn't know about the internal operations and available information in a dealership. Then my role reversed into a dealership technician and I was able to learn about and correct some of the assumptions that I'd made. Moving into training requires keeping an eye on what is available to
As mentioned make sure your usb has enough storage. You will format it and upload the data using GM SPS. It takes a while to this (20 minutes or so). I carry 2 usb’s, one for saving screen shots or whatever else I may need, and one that is blank for muti-media control modules that I can easily erase/reformat when needed.
Well I will give it a try and hopefully it goes well. Thanks for the info guys
With the new hmi module in the radio says Calibrate Device. I have downloaded the info from sps to the usb stick which is formated to fat32 and installed it into center counsel usb port. The radio hasnt said anything else so i'm not sure if it is actually transferring data from the stick to the hmi module. The stick did flash at first when plugged in, so i'm not sure if i need to just leave it
I did get this done, when i was in sps it listed programming and usb file download. I did the usb download route. I recieved a call from a guy from autologic that said i need to program it first than do the usb file transfer. If i look up programming in mitchell it only states to do it with the usb. I also found a gm tech link bulletin that said a usb programming event is sometimes followed by a
