Mini maxx help

So I bought a used mini maxx street that has mcc tunes still on it from previous owner. I know that I cant use these tunes but was wondering if there is a way I can delete them off the sd card just to clear space and avoid any confusion? Also do I still have access to the original emissions on tunes that came on the tuner so I could use them until I can get everything to do deletes with new mcc tunes? Sorry if this is a dumb question im just trying to figure out what im doing before i screw anything up. Any help is apprecaited, thanks.

Yeah you can delete the tunes and as long as it's not vin locked , you can use the canned tunes . Let me know if I can get you mcc and some tunes.

Alright thanks, ill be getting ahold of you soon
