Thread: Using TMC in Garmin nuvi for free

Dear All,

I have Nuvi 760 with GTM 20, which i bought back in 2008. I tried the method described in this tread, and can't really get it to work.

(1) If i use TTN srevices, it would work for a while, then it became expried.

(2) If i use NAVTEG, then it also show that it needs to be actiivated when GPS & Provider signal become aveliable. But I'm in L.A. area, it should have signal, still not working. Any fix on this??

Please help~!

THANKS. I try install this,

k, here's the deal. I have 2 codes for Navteq. One is the default from Garmin that came with the Nuvi device for lifetime (ad supported traffic). The other is the one with no Ads. I also have the TTN (clear channel) that I used with jetmouse.

The TTN is the default in my area but it blows. I really dont want to use it. When I was Vegas recently, the stronger channel was Navteq but ads were shown. In my case the the ad version is overiding the non ad and three codes appear on the Nuvi traffic logs.

maybe I entered an invalid navteq code? i thought i read somewhere that there are two different navteq keys as there are ttn keys. Apparently 28935 for NAVTEQ will not turn off the advertisements so there appears to be a different code to enable NAVTEQ and disable ads?

any way of removing TTN?

My suggestion, why not post here the codes u have?
Second, Navteq needs always to have the Codes for USA and Canada saved in your device, even you are not in Canada.
Similar like Destia Nordics which requires all 3 codes.

tom, r u referring to me? if so. i dont have the codes. i just entered the codes jm gave me into my device. unless u want me to give you the codes listed in garmin's diagnostic screen?

My answer was directly after your posting, so yes I referred to your post.
What I meant, when you generate the code for USA Navteq, then you have to generate also a code for Canada Navteq.
If you only type in the code generated by JM keygen for USA and not also the code for Canada, the subscription stays invalid

Tom, in my case the navteq code is included with my GPSR but with adds.

When I entered the non ad version, it took the code but I still receive ads in the USA. The original ad versioned sub still works. Are you suggesting that one needs to add BOTH USA and Canada subs to get the non ad version?

Do you know how to remove the TTN/Clear Channel sub? It's the priority frequency and it only works kinda, monday to friday. it's pretty much useless in my area yet it is on a more powerful [channel] than navteq.

If I would know which code is for the Ad-Version, then you could use the keygen to generate a code to remove the Ad-Version.
But definetely you need both codes.

In China TMC is free. Below the info from Garmin

I'm trying to unlock a traffic receiver for a 750 and it's not working. It never changes from "expired." With the unlock generator, which software product should I select, "Garmin Mobil PC" or "Garmin Mobile XT?" And do I need to enter the code in all caps?
