Thread: Using TMC in Garmin nuvi for free

Thanks Giomen, i'm aware of that thread which i posted in extensively and it refers only to the 2012 models with integrated receiver and TA-20 power cable [i'd not heard of TA-10 either]. I wasn't aware of any 2013 with built in receiver other than 1x2/4 range. I guessed that it's this one he had:

Under 'Комплектация' ['Complete Set'] which i assumed was the usual 'In the Box' tab it has 'Антенна для приема трафика' which translates as 'Antenna for receiving traffic' which sounded more like an included accessory than an integrated receiver to me. [Just so you know i did research it before i answered him which i did because his post had gone unanswered for nearly a day ....]

Also on re-reading the post, I think he's asking if he can add another TMC sub to it using this method or only by paid.

TA-10/20 is named as traffic antenna cable vs GTM known as traffic receiver cable:

P.S. Neil - why is Russian local page for quote. You have bought your Garmins in Russia? And you do not fear the real brown bear behind the counter. It is very cool!!! I was heared that kangaroo is not pussycat too. But we are going for Garmin in Australia if we could have possibility

AH! The penny has dropped. Thanks Giomen. Yes i knew that the vehicle charger cable was used as an antenna for on-board traffic receivers [much as a mobile phone earpiece cable is used as an aerial for radio reception], but didn't make that connection until now [Bl**dy translations!]. So, is that 'version' of 2497 only available in RU region or are there other on-board regional versions in EU as well?

Also, can you add a JM sub the same as with an external GTMxx?

PS: I've bought bits and pieces from Russia. 2nd hand screens, GTM21 recently [it had a US 3 month sub on-board strangely], but never a new unit. One of the few types of units i don't own is an on-board traffic model [someone was going to go to Germany last year to buy me a nuvi 150 for Christmas but spent the money on Vodka instead i think ].
Best you send me one of those Ruskki 2497s this year or i'll sic my 'roo onto your bear's sorry saggy brown a*se!

I do not know Russian market. In Russia is not office of Garmin and so buying device is dangerous. Very bare complectation, overpriced cost, bad service and problems with guarantee take place. So on garmin.ru are many info that do not correspond with reality.
But I hear what model with built-in traffic receiver sold in many country and it have problems with SW in opposite to external GTM. But angelozip wrote that built-in traffic receiver work with JM:

The cable carrier is a simple power cord (TA20), but Traffic does not work with non original Garmin cable (still need to test the cables GTMxx with receivers ).

The good news is that the receiver built-in accepts keys generated by JetMouse.

Question is only in SW version for traffic receiver. For external GTM problem is fully investigated on this forum. But not for built-in version. You must post ad that the experimental rabbits is required.

Either i missed that in Angelo's post about the NA 24x5/25x5 with traffic receiver on-board accepting JM subs or had forgotten it. That's essentially the same hw as 14x/15x i think [same PCB P/N anyway] so probably all of them share the same traffic module including 2xx7 i guess, so Philipych can be the experimental rabbit if he chooses.

Your EN is better than Giomen's and i understand him just fine.

Thanks for reporting back. Glad you have your added traffic sub working.

PS: Our humour is an acquired taste though. Even native English speakers don't really get it so don't worry ...

Friends , makes sense the TA-20 cable also serve as antenna, but would make more sense if there was at least a small antenna embedded in the body of the gps, as exists in much smaller devices like mobile phones ( that have GPS antennas and others.. ), that is, would have felt the traffic work without the cable connected, even if partially. The fact is that the traffic receiver built-in GPS does not work without the cable, then it's likely that it also have some power line specifies in the cable to the receiver traffic. It is also worth remembering that, as already mentioned, a user received of garmin a report that another cable with a different part number manufactured for years (I think ), would also serve as a substitute for the TA- 20 [Only registered and activated users can see links. ] post # 13. It seems so strange that a power cable produced at long ago has embedded antenna and serve to activate the GPS receiver traffic of recent gps, ie, I suspect about the veracity that the function of the cable is only to serve as an antenna .
A likely need of extra power supply to the receiver could be the major energy consumption that would degrade the battery, or Garmin's strategy to force the use of its accessories (cables). To solve the question only opening the other mentioned cable (and a TA- 20) and to see if in fact they have built-in antenna. By the way, the GTMxx cables are divided into two parallel parts visible externally, where a corresponds to power transmission and other for antenna (I've opened some to check out as well). As the receiver is in the cable has felt the main antenna, and connector for an auxiliary, stand in the cable also.
