I followed these steps and I now have TTN and NAVTEQ Lifetime with No Ads on my Nuvi 880. FastIMG Unlocker? Probably not related but given the oddity about the Mapset name, who knows? I just took everything that worked for others and threw it in there. Adding TTN USA, power cycling and then adding TTN USA and CAN. NAVTEQ seems to hold no matter what so adding NAVTEQ CAN is probably not necessary. Is this the magic step? I don't know as the discussion included hex code explanations of why 4095 was the important number. Incomplete power cycling is almost surely the problem for some.Ĥ) Must download and use Jetmouse 1.3 Modded for Traffic. So turn off Nuvi, take out battery, unplug GTM 20, disengage GTM 20 from Nuvi.

The Nuvi provides power to the GTM 20, even if you unplug the GTM 20 from the socket. Therefore, Map Info will read "CN North America NT 2013.10" Next Line: "All" The mapset name might have been a problem for some.Ģ) Do a complete power cycle.

Not sure why but it's something I came across. To me, these seem to be the important details:ġ) Make sure the Mapset is named "All" exactly with the lowercase l's and no quotes. If you're confused by the instructions, I'm sure others can explain Jetmouse 1.3 v Jetmouse 1.5 0, 0, 0 v 0, 0, 1 etc. I'm just sharing what worked for me in the hopes that they will not have to read through the hundreds of pages that I did on I hope this works for other Nuvi models other than mine, as I expect it should since the problematic device is the GTM 20. Please note that I don't check these boards often so if this does not work for you, I'm sorry, YMMV. My Steps For Permanently Activating Total Traffic Network and NAVTEQ On GTM 20 and Nuvi 880
