mm3 help

[Cumminspower26]

I've been dealing with someone to get my SD card to read in my MM3.

I've been dealing with this for a while, and so far, no results.

I've gone through 3 SD cards and the same issue.

They did multiple SD card re-formats and the same issue.

I get invalid SD card data when I go to the main menu, and I don't have my RT tunes cause of the SD card issue.

I have replaced my batteries cause we figured it might be causing voltage issues and the same issue.

The longest time I had after SD car reformat was like a week and then back to the same issue.

Idk know what to do.

I'm debating about returning the truck back to stock and can't do so cause the SD card issue.

Contact MM3 and see what they have to say.

I assume your MM3 has the firmware up to date, and you're using the MM3 update agent to restore the contents of your sd card after reformatting?

What format did 'they' use when reformatting?
