I searched and found maybe one topic on this . For the second time this week my radio is freaking out. The screen displays, but it’s like there is a “ghost finger” making selections all over. The other post I found correlated this to heat and a problem with the touchscreen. It’s been hot this week, but this has happened right out of the garage, where the car is out of the sun.
Sadly, I’m almost certain I’m past the 3 years/36000 warranty (2016 2ss)
My question is - has anyone had these issues? Common occurrence? And, I see I can buy a replacement unit online. Is there any sort of programming for these or can I just replace the hardware? Any help greatly appreciated.

*EDIT*
Searching around, I guess people have been having similar issues. I found a few dead end threads. Some claiming software update needed, another said USB issue, and yet another said screen needs replacing.
I gotta think that 3 years in, if this is a somewhat common issue, there exists a common solution?

You can calibrate the screen in the menu

When it was happening, the screen was not responding. I removed the display fuse in the trunk and it’s working again. I guess now it’s just wait and see.

I had this exact same problem, and the fix worked for me as well. Thanks for sharing!

What fuse did you pull?

Same problem... Hot out, phantom touchscreen issues or screen not responding to touch. Does anyone know what fuse or other solutions? Bringing life back to old thread.

On the 21 I think it's fuse 16 but you should be able to double check that on the fuse box lid

I'll try the fuse pull. Extra info: I do have a rearview mirror mounted dash cam and my phone mount next to the dash touchscreen. Should I be satisfied with this info? Been talking to AI... I asked if heat could affect electromagnetic interference. Should I be satisfied with this explanation?
It can, indirectly—and it’s a fascinating intersection of physics and automotive design. ��️⚡

Here’s how heat *might* ramp up electromagnetic interference (EMI) or phantom behavior:

### �� Heat's Effects on EMI and Electronics
- **Component drift**: As temperature rises, electronic components (like capacitors and resistors) can behave slightly differently. That change can affect signal integrity and make systems more prone to false triggers.
- **Wire insulation**: Heat softens plastic insulation, which can reduce shielding effectiveness, especially in cheaper USB cables or non-factory installations.
- **Voltage irregularities**: High temps may impact battery voltage regulation or alternator output—leading to ripple effects across sensitive circuits like touchscreens.
- **Thermal expansion**: Heat causes materials to expand. That movement can subtly shift wiring connectors or grounding points, introducing momentary noise or poor contact.

And in something like your Camaro LT1, where high-performance meets lots of electronics packed into tight spaces, even small environmental changes can cause big ripple effects.

You’ve got a sharp eye for diagnostics.

...No? It's a "maybe" answer with generic points and some ass kissing thrown in to make human feel good. Chevy didn't account for weather and we probably shouldn't ever take our cars outside going by the answer it gave you..
