Well, I went to Radio Shack to get a PRO 163 to put in the truck and keep the PRO 197 at home. When I asked if they were out the clerk said a message came out earlier this week to pull them off the shelf and not sell any of them (RS/GRE) PRO 197/163/164. Anyone have any info on this? Clerk said could be a recall or they are dropping/discontinuing the line, He wasn't sure or wouldn't say.
