Thread: GTM36 and GTM26 problem with TMC on nuvi series 2xxx and 3xxx

Loly, if you say you fixed the "Invalid connect time" changing the date of 2020 to 2011 in GTMdata.xml, although we are in 2012, and the warning still appears in the screenshot that you posted, I can only conclude that you sent the wrong screenshot by mistake, and that changes everything. Now I say for sure that it is highly likely that you've overwritten the original signature (erased) with of Jetmouse and from there can no longer tune, the same problem described in post 41, which seems to be universal. So, do not worry about reinstalling firmware, is not around. Post again the screenshots of the GTM36 nuvi3490 update, to confirm the problem. If you really deleted the original signature, the traffic will not work.
As I said, we'll have a good work ahead to try to resolve this issue ..
