I put 006B154600.GCD, which is only 1029KB, into the RemoteSW folder. No update. So at this point I kind of give up. There are known issues with GTM70 updates rendering those traffic receivers bricked. The last thing I need is to have my GTM60 bricked. It seems to me that Garmin made a little boo-boo, so lets wait and see if they correct themselves. I'll keep an eye on this issue, once I come up with some ideas I'll post. Thanx for the effort.
