Well, thanks for all the replies, I was reading on the FCC site, and digital data like Text messages and GPS location info is allowed on GMRS. Since Btech makes a radio that sends texts and gps info, that is probably what I am hearing.  So for now, I will just set a tone on that channel when I hear the digital data so I can't hear it. Not much else I can do.

Based on the actual track-record of FCC enforcements since 2012, statistically speaking, they wont do anything.

In my opinion the FCC won't do anything unless it interferes with a life and death situation.

That’s exactly the kind of thing you should turn in to the FCC. 

There is a full blown MotoTrbo DMR repeater that has been eating up 462.700 in my area for over 6 months. Running my MD-380 DMR HT with 3rd party firmware in promiscuous mode ID's it as MotoTrbo but can't get much else because it's also encrypted DMR. It forced a long time local repeater to move frequencies because of it. It sucks but not much I can do about it, had to remove the frequency from my scan list.

No, but people do it all the time. Not just DMR but P25 and NXDN also.  It is much annoying.

Depending on the DMR radio it might have a monitoring or promiscuous mode. That allows the radio to decode any DMR signal without the necessity of using the correct color code, slot number or talk group. For example my D878 has this feature. Turns out to be handy at times.

Digital data transmissions.Digital data transmissions are limited to the 462 MHz main channels and interstitial channels in the 462 MHz and 467 MHz bands. 
But, that’s not the same as digital voice, such as DMR.  Digital voice is not allowed on GMRS with the exception of some sites that applied for experimental usage.
