HMI Programming - what is needed?

vinsanity · September 14, 2015

I see a lot of people are choosing to pay $100-200 to send their HMI upgrade off to be programmed.

What is actually required to do the programming? Is it not something that can be purchased and done ourselves? I am considering upgrading my IO4 to an IO5 or 6, and can't seem to find any info online on how to do the programming myself. Is it an expensive system that is needed to do it? Just curious...

If you are talking about the unlock/video in motion/texting etc you don't do it yourself you have MVI do it for you.

That's exactly what I'm talking about. Can it not be done by anyone with a certain adapter or computer system? Why does it need to be sent to MVI or someone else to be done?

It needs to be sent to MVI because they are the sole supplier of the programming by design. It can not be done using an off the shelf computer or adapter etc.

To be clear MVI is the ONLY company in the world that offers the HMI unlock service.

You also can NOT do any programming yourself for any kind of upgrade on these systems...just FYI. This is all very specialized...even dealers have a hard time getting it correct

FYI....check out the new upgrades available for the I03 systems and there is not a dealer on the planet that will offer this

Full length video will be available after purchase of the kit...call or text with questions!!

So would a dealer technically be able to enable video in motion or nav entry in motion ?

I doubt anyone at MVI is gonna give you any insider tips but I don't see why you couldn't do it if you had enough exp and knowledge on the subject, or maybe if you are a straight hacker. Maybe not, just my take.

No, you're right, it's do able but I can promise you the juice wouldn't be worth the squeeze or I would be looking in to it.

I believe the newer ones are running Linux, Id be interested in just understanding the process (even though I probably couldn't do it myself)

I found this .. only works to 14 it appears but interesting nonetheless

That is for a different platform. The issue isn't just the software but the communications protocols used to talk with the hardware to access the software. So say you figure out a way to effectively communicate on the GMlan or the MOST bus, you then have to figure out how to decipher the information that is being passed and what is primary and what is tertiary.

The source code is readily available, but getting all the pieces to fit is the insurmountable task and if it were cost efficient people would of figured it out. As it stands, this is what I do for a living, but my time comes at a high premium to the point where it's more economical to depend on guys like Chris and MVI who can do it because even if I invest the time to figure all of it out I'd never get a return on my investment as I wouldn't be able to provide the level of service that they do at an economical price. If I thought the prices they were asking were unreasonable it might give me incentive to do something but I happen to think they are reasonable and am glad someone provides the service.
