Hi everyone, I have a 2015 GMC Terrain with IntelliLink, and I’m trying to update the radio manually via USB. These are the software versions currently installed:

84062132 – E0.11.20.40
77777777 – E0.00.41.55
84019249 – C1.11.20.40
84062134 – C1.11.20.40
84019246 – C1.11.33.11
84019248 – 00.07.23.15
84019247 – 30.67.09.04

Does anyone have a USB update file for any of these modules? Or know where I can safely download it? Thanks in advance!

Don't download anything someone sends you or obtained on the internet. There are no public legit files. Only GM TDS has them and they are based on VIN and config.

It's better to find out why you want to update and fix the problem you might be having.
