Hello,
Thank you for contacting Whistler. At this time, the DMR update is only available for the Whistler brand scanners. Although the RadioShack branded scanners are manufactured by our company, we do not control all decisions regarding those products. We continue to support these RadioShack models with updates for issues pertaining to the original product features.
