Well, it was nice while it lasted I guess. Would be nice to have, but I guess kind of ironic to be too hung up on online features when the primary usage is as offline nav in the car.
Would be interested if there is a fix for this in the future...I guess from what you're saying each time the modders circumvent the server blocks its just a matter of time until NNG figures how to block once more...
Did you ever find that post you were looking for that had USA TMC sys.txt code? Was it different than the one I linked here previously?
