Thread: Using TMC in Garmin nuvi for free

To delete the signature through the normal process you really need the FID, PID, and RgnID VenID (this should be zero) to generate a key that will erase the signature inactive, but strictly speaking the signature inactive will not interfere with the news that you will install. But to ensure that a signature do not interfere in the other, generate a signature for annulment with the parameters of the new signature, before installing the new one. If the inactive signature is deleted, simply install the new and the problem is solved, but if she keeps installed, indicates that the FID is different and refers to another provider/country and will not interfere with your new signature (dont forget to reset the GPS and GTM20 to see if it was deleted). Later, with calm, you can try to discover how to eliminate the signature inactive.
