Is this correct? Maybee it is necessary to have FM- connection?

It depends on you GTM model
It is correct and works correctly (in my experience).
It may change the details when switched on to receive satellites and radio signal at the same time. Sometime this does not work but data still received.

Works fine on 765T v4.1 with GTM 21 v5.5.

Thanks!

I got carried away testing these codes and it says maximum number of subscriptions reached. Is there any way to remove some? (as I didn't really prioritise the ones I put in). I tried changing the VendID to 0 and rentering the code of one to remove but that just seems to disable it (so it doesn't show in the list), the same message still appears on trying to add a new sub.

Are these stored in the TMC or on the Nuvi? If a sub can't be removed, which do I need to replace to sort out this problem? (If on the TMC, if someone else uses the TMC will they be able to use the traffic codes I entered or are they tied to the Nuvi?)

The codes are stored in the TMC antenna.
But u are writing above that u have Nuvi765 with v4.1, do u mean the FW? Thought its on v4.0

Hi Tom, Thanks very much for your reply!

Yes, it's 4.1 (in Settings > About > Software Version: 4.10).
I turned it off and on several times. I also tried to do a reset (hold bottom right corner and select to erase all user data). Still it doesn't solve the issue - it tells me maximum number of subs added.

Has anyone actually managed to remove subs - I read elsewhere that once subs are added there's no way to remove them?

So maybe I have to buy a new TMC?

Hello there, I am trying to get my TMC working on Garmin Nuvi 760 with GTM 20. the distributor says that it is not possible. I want to use the dutch TMC, any solutions

Any updates about TMC in Israel?

So, I dug out my old GTM-20 and read every post here, but, like others cannot get rid of the TTN entry no matter what I enter - Navteq works fine, but I preferred TTN - and like others here it shows active for a bit then goes expired - I assume there's another FID code in the receiver that is overriding the ones published here - and I see no way to easily determine what it may be.

At least Navteq traffic works - who am I to look a gift horse in the mouth?

Older posts mentioned issues with ads - one poster said he got no ads with his 750, but did on (I believe it was) a 765 - I saw no reply to his comment and for posterity, I figure that loose ends should be tied - there is no ad support in any of the XX0 Nuvis - they all ignore ads, plain and simple.
