when I purchased Uniden BCD536HP, I paid to have them install DMR. I see Caterpillar is DMR. I used ARC536 software to download Caterpillar DMR using Mapleton/Peoria site, and the Peoria TG.but hear nothing. not sure if i need to do anything special to install DMR talkgroups........... My question is Has anyone heard anything on Caterpillar DMR. I live 20 miles north of Peoria
