Even if I were to obtain a traffic receiver ID number, where do I input it in the Jetmouse Keygen? There is only a Unit ID entry. Is that supposed to be used to input the ID's for both the Nuvi and the GTM 20? I am confused.
    I assume you are doing all of this with both the GTM and 760 powered up (you must be to have gotten an ID).

    That ID you got in the ADD Subscription dialog IS the 10 digit unit ID from the GTM 20 (and the ONLY one you need for the kegen). It is NOT the unit ID for your 760.
    If you want the UnitID for the 760 look at
    Tools > Settings > System > About
    and your 760 ID will be in the upper left hand corner. You will see that the 2 UnitID's are different.

    FYI - The GTM 20 UnitID and any subscription Keys you enter are stored in the GTM, none of that data is saved in the GPS which is why A "Traffic Enabled" GTM-20 will then work on any 7xx GPS or any model that is compatable with a GTM-20. The Traffic interface on the 760 is just a mechanism for you (the user) to communicate with the GTM for the purpose of adding or renewing expired subscriptions.

    Thank you for your immediate response. You are absolutely right. I got the ID number and used it to generate the traffic codes. I was able to obtain the Navteq code and it works perfectly. Sadly, like everyone on this forum, I have been unable to obtain a code that will last for more than a few seconds for the TMC. There are no specific instructions as to how to obtain a permanent subscription. I have pretty much tried everything except using the modified Jetmouse 1.3 key generator which I can't seem to find anywhere. Perhaps that is the key, I don't know.

    If anyone has the correct instructions to getting it to work properly please let me know. After going through over 400 posts it seems like the original instructions in post No. 1 do not work for the TMC subscription as they have been put up.

    Let me ask you this....

    Before you tried to enable TMC on your GTM dit it already have an EXPIRED subscription ?

    To get lifetime Clear Channel Total Traffic for US and Canada "TTN"
    ************ Tested to "EXTEND" an Expired subscription
    IMPORTANT: you MUST use the modified keygen "jmgkg13modTMCExp.exe"
    use custom mapset with a family ID of 4094 (some say 4095 also works, I've never tried 4095)
    NOTE: If you run the generated key through the Key Parser it should reveal a valid key with
    a mapID of 28992 and an expiration date of about 50 years from now.

    Can anybody provide me a link for the modified for traffice Jetmouse 1.3 key generator? I can't find it anywhere. All torrent downloads but none seem to download the actual program.
