I will try to contact Garmin, maybe they'll do the same for me as for williston - thanks for the tip. New cables are readily available for $80-100, but that option IMO is not worth it. The bad news is, I now have no back up cable, so my challenge is to either fix the bad one or find a replacement without having to pay for a new lifetime subscription. I discovered there is a good thread on the GTM 20 cable and traffice issues here: The good news is, I can have good traffic info on either unit by using the good cable. Diagnosis: the shorter cable is the culprit. When I tried that cable on the 765T, it also worked! Just to confirm, I tried the normal cable I had been using, the one that came with the 765T (shorter, heavier GTM 20 without LEDs) on the 760, and sure enough, no traffic. When I tried the 760 with its own receiver cable (the longer but lighter GTM 20 version with LED lights), it began picking up the signal and displaying traffic again. It turns out, the FM RDS traffic signal is still alive and well in SoCal. Based on williston's comment, I decided the hardware was worth checking into a little more. But I did not think of that as a possibility for this traffic problem, because the power connections are stable. As others have reported, I have had the intermittent power issues related to the cradle, and have replaced several of those.

If anyone knows how to find this on a Nuvi 760 or 765T, I'd be interested to know. Regarding tli's post, there is nothing I can see like what you posted for your 1450LMT in my units menu system, and I see no file on either unit that looks, by the file name, like it is traffic related. However, I do not see on either of my units, a 760 and a 765T, anywhere were it gives me an indication of what the traffic firmware or database date or version is. I decided to give it another shot, and installed and ran it without any trouble, but there were no software or other updates available for either unit, so I do not think that was a factor in my not getting the traffic signal.

Thanks for all of the suggestions! For map updates, I have been using Map Updater, and had not used Garmin Express for several years due to the trouble it was causing at the time.
