Poor Traffic Reception

This is an issue that was introduced in firmware 3.90 on the 7x5 serices. It is discussed in this thread: http://www.poi-factory.com/node/27301. See the post from DorkusNimrod a few posts down.

What was suggested to me and what improves my reception when I visit Phoenix with my GTM-20 traffic receiver is to loop the power cord (which is the FM traffic antenna) over the rear view mirror rather than have most of the cord down by the vehicle console.

{edit} Whoops, I see it may be a firmware issue for some. Thanks. My mirror loop does increase the reception range for traffic in fringe areas, though.

At this point you should wait for a fix via Garmin. Rolling back a software version can corrupt your Bluetooth.

Bluetooth has its own firmware. I had to roll back my BT to a previous version to again successfully receive calls in my 660. I posted a few times about that problem, and the problem is still solved with the BT firmware rollback. I don't think a traffic firmware change should affect bluetooth.

I think it might be unit specific. There are numerous reports that rolling back a 760's 4.1 or higher firmware to a v3.x version irretrievably bollixed the Bluetooth, to the extent that it had to be returned to Garmin to be fixed. It might not be a problem on a 660 or a 765, but it's worth doing a reasonable amount of research before you do a rollback.

There may be a software bug, but the traffic receiver antenna is in the cord. If it is coiled up down low you will get intermittent reception. Tie it up in a loop and see what happens. There are other threads on this issue.

Thanks for the info

I use a bean bag mount and stretch the power cord up so I can lay a loop or coil on the dash and hold it in place with the bean bag. Lying on the dash it can't be considered as "an obstruction to vision" if it were looped over the mirror in SOME states.
