I’ll upload it to the site later. Many folks have asked for this file a few times. It’s great to have it now available for download👍.

The vehicle is a 2016 Impala, and the VIN is 1G1155SA7GU134038.

This is NG 2.5 HMI IO5 84028491.

When I put the file in the USB and connected it to it, it said, "Invalid update file.

The update file below is not valid: 84156702.mnf" and does not proceed with the update.

Can you please let me know what the problem is

Sure - your problem is that this file is not valid for your unit, and you need another one...

Your unit is IO5 (no NAV), while this update is for IO6 (with NAV).

물론입니다. 문제는 이 파일이 귀하의 장치에 유효하지 않고 다른 파일이 필요하다는 것입니다.

귀하의 장치는 IO5(NAV 없음)이지만, 이 업데이트는 IO6(NAV 있음)용입니다.

Thank you for your kind answer.

So can you tell me where I can get IO5 firmware?
