In addition to current maps I also have been using R&R for many years. I used the trick of copying the entire disc onto my desktop and letting operate from there. Fast forward and I cannot get my pc to even recognize, open or otherwise detect the disc, or the file on my desktop. In fact, I cannot get the disc to even auto start when I put in the drive. Any sage advise from the old timers here? I really don't want to give up the use of RnR as it has a wealth of info that modern Garmin maps no longer have.
