Hyundai Head Unit Hacking

Allowing users to turn off crap like the "please fasten seatbelt", "do not drive while impaired", "do not change navigation while driving" or whatever common sense announcements that appear as forced modals every goddamn time you start the car.

You know that bright yellow ugly-ass label on the sun visor? I used to rant about those. They’re not removable and… like I said, ugly.

How I wish that was my only complaint. Now the nav scolds me, the seatbelts hector me, my passenger needs to swear some sort of oath that they “are not driving”, etc.

I hate warning labels. For every useful one (e.g. “Pinch Point”, “Not A Step”) there are ten more that believe me to be a hapless infant.

You can almost certainly get a tool to code all those nags off, or at least most of them. $600+ for a Launch x431 in my case, but worth it.

Unless you're a mechanic that needs to operate on a wide range of cars, I suggest instead looking for a brand-specific scan tool.

Universal scan tools like Launch/Autel/Topdon/Snap-on are good in terms of the wide range of makes they support, but they lack in depth - you may not always get the full feature set especially when it comes to "coding" (aka setting configuration parameters) or anything beyond fault codes, live data streams and actuator tests.

Brand-specific scan tools on the other hand only cover their specific brand but generally offer a much deeper set of features.

This is why I love BMW. They have the entire coding/updating software used at BMW dealerships online for download (not-official). You can change parameters for almost every feature on the car. Anything from disabling headunit warnings to injector control.

BimmerCode / BimmerLink makes coding/customising supported BMW models even easier, as long as you've got a mobile device and an adaptor (e.g. OBD II to Bluetooth, inexpensive), you can DIY coding and obtain visibility into a lot of the car runtime parameters (e.g. engine oil temperature, boost, etc.) - can connect a screen and display whatever you like, turn off the pesky `ASD` (fake exhaust sound pumped into the cabin via speakers...).

What's more amazing these days is that technology like `bootmod3` (bm3) makes flashing (remmaping) stage one as easy as 1-2-3. One needs to understand what they are doing though.

I may try this, although seems overpriced:
