    I went out and bought another powercord w/ traffic antenna. Same problem. The unit itself seems to only use MSN software. Do I need to change my firmware to allow other traffic subscriptions? Also the above sequence "menu Tools, Settings, Traffic, Subscriptions" does not exist for my Nuvi 680.

    The best I can do is "Tools - Navigation - Avoidances - then check the traffic box

    Just stuck on how to get a TMC ID or which cable to buy exactly. Those things aren't cheap and I don't want to keep buying them using trial and error!

    Any help is appreciated.


    Edit: Found a GTM-10 10 digit code. It stays the same regardless which antenna I use though.
    You need a GTM21 - about $40.
    Plug it in.
    Power GPS
    turn off gps
    Use garmin webupdater to ensure gtm correct firmware
    power up gps again with gtm21
    you should have options to add subscriptions.

    PS most gtm come with a subscription.

    I had originally replaced an unlocked "gmapprom.img" file, along with placing .jcv file in the ./Garmin/jcv/ folder and gmap3d.img in the ./Garmin folder. However, I did not replace the gmapbmap.img. After c550 rebooted, it recognized the map and works with the recently found, favorite, and places of interest (Food, Bank, Auto services etc.) addresses. But strangely, I can't enter an address on my own. When I tried, it asked me to spell the state, which I did, but showed that it was not found. I tried entering other states (US) as well, without avail. So, I can't go ahead in the menu to enter full address. The same problem I face with the jcv (intersection). Now I am left with only option of finding a route by using browsing map where I have to select a point near I intend to go. Once a point is selected, GPS works fine... Here, may be it is worth mentioning that I have used an already unlocked map and not unlocked it myself using Mapsource.

    Now, I replaced gmapbmap.img file (originally was just 5.8 MB as against new one around 50 MB) in addition to the above said configuration. It does make a difference in the way it recognizes Traffic. Now, in the setting it appears that I can choose either auto or available FM bands (e.g., 97.1 or 98.3 etc) after running search. In practice, when a search ends, I see four different frequencies that shall provide traffic updates in my area. When I force selection, other than 97.1 FM, nothing else get selected. However, this selection happens on auto mode also. I can see TMC light turn green when 97.1 is selected. But, it does not work. It does not give me any updates. I tried this with the "traffic" checked and unchecked in avoidance menu while travelling to work with turn by turn GPS (I use WAAS for better accuracy) enabled. I traveled on Expressway in order to give the traffic update a full chance. Under the subscription, it shows TTN (US, Can) as well as Navteq (US, Can) Lifetime subs. I have additionally entered the codes for Canada separately for both services and received notifications of successful subscriptions. However, I don't see any entry for the same. I had a "New subscription" before that had appeared after trying a code generated by the keygen version 1.5 by JM without checksum fix. But later on, I could probably remove it successfully by entering a code generated by supplying VenID 0 as suggested on this thread. I have tried 1527 for the code generation as suggested in the posting #10 and it notifies that the code was applied successfully. But nothing changes in the subscription list. I am using:

    Garmin Streetpilot C550
    GMT20
    Software Version: 6.70
    Audio Version: 2.20
    GTM Software Version: 5.50
    GPS Software Version: 3.00
    Bluetooth Software Version: 3.40

    My Experience with these subsc.:

    1.) add and remove a subsc. is only visible after a restart.
    2.) DON'T add to much subscribs. If there are more subsc. than 8 active at the same time, TMC dosn't work any more. In my opinion after the GTM scan for a FM-chanel it try's if any subsc. fit's to this channel.It starts to descrypt. If there are to many subsc. you get a timeout (for all cannels). After a few trys you get a mini-USB- Reset (Powerup). Then you don't get TMC for hours.
    If there are only 6 subsc. it will work fine.
    3.) Use only one DESTINA key, not all 4 keys. It will work in FI,PL,SE,NO.

    Thumbs up Netherland

    You've asked the distributor? My expirience is that the garmin support don't know much about their devices. It's "not possible" or you get a RMA to send the device back to the garmin repair center. I've got a few RMA's but at least I fixed all problems by own.

    I have a 3790T but it does not have any traffic option in the menu. I'm new to Garmin after TOMTOM so am a bit unsure as to how to enable? Help!
