Thread: Nuvi 40&50 in German is Nuvi 140T&150T (Traffic!!!)+ Nuvi 40/50 to 42/52 tests

Maybe Traffic data comes from satellites or from another source ?
Can these nuvi receive traffic on battery power ?
Any ideas.

No, traffic function didn't work on batterry power, on AC adapter cable or anyone other cable except TA20.
I think, it will work with GTM. Tomorrow I can check it.

Sorry I missed some action guys. First sleeping in the arms of Bacchus, then earlier today was doing major upgrades and loading Win8 to my main PC. Thanks for the PM to alert me loly. Have abandoned the PC to work on this exciting project. It's just after midday here now so I suppose most of y'all have your heads under your wings in the NH. This is what I have done:



This looked good so far:



Then this, tried 3 times & got same result so that is not gonna work:



Have I done something wrong? Here is the rgn i used: [Only registered and activated users can see links. ]

Unit flashed back to 40 v2.70 fw OK.

Tried with combined fw GUPDATE.gcd but really didn't expect that to work and it didn't of course. Unit stalled on initial screen for a while:



Then it booted and ran normally. No change and no GUPDATE.gcd in .system folder.

@loly
The fw_all.bin of 140/150 is huge compared to 40/50's. Is that right? BTW, actually i do have a 50 but it's near-new and LM, so playing with the 40 as the 'sacrificial lamb'. Don't want to risk the 50LM.....

Credit card is my favourite tool too! [Only registered and activated users can see links. ]. Lately sometimes been using an expired iTunes gift card as i've found it to be a bit firmer than a cc which makes it better for some units.

Angelo, that linked post of mine also describes how i open 3xxx without risk of damage, gentler and safer that a case pry tool i think.

Captain.snail, welcome aboard Sir! You nick belies your machine-gun speed of posting, another worthy addition to the Noeman gurus. Not me, i'm just a 'blunt intrument' man, i'm not 'fancy stuff capable' but happy to test.

@Neil
Nuvi 40/50 and Nuvi 150 have different hardware version. I think, fw_all.bin of 140/150 doesn't work on nuvi 40/50.
And it is interesting to me, how we can convert 140/150 to 2xx5 series or to add missing functions (look at screenshot of about pages).

The loading addresses of firmwares for nuvi 140/150 and nuvi 40/50 are different (0x00080000 vs 0x10032000), so you can't easily "convert" one to the other.
But they are equal for nuvi 24x5/25x5 and nuvi 140/150, so it may be worth trying.

@lolypop000
Yes, it work with GTM35 cable.

@kunix
I spoke about convert 140/150 in 2xx5, not 40/50 in 140/150.
Possibly it's not easy. But i hope it's real.

@captain.snail; @kunix
Yes I too thought that's the problem, different hardware versions and maybe differing address loadings. However, before i saw the further posts i noticed that c.s had uploaded v7.27 gupdate.gcd in a previous post so i tried that:

Yippee! Lookin' good, baby!!:



but then... bummer!!:



Here's the .rgn if anyone's interested: [Only registered and activated users can see links. ]

Being a wimp, i kept it connected and flashed back to 40 v2.70 fw. Any expert opinion on the risk of turning it off and on to see if maybe, just maybe, it boots as 140T after getting 'System Software Missing'? Or do you think it will brick for sure, kunix?

If you want to play with 2455 i have one, and also a 2350 but i suspect that there are big differences there. Maybe 40 is more like 2350 (just putting it out there, i wouldn't know) and 140 is more like 2455 (it seems the latter two have the same ARM processor maybe differently clocked)?

My 2455:



I hope that earlier screenshot of yours is an old one, Капитан, or you best update it..lol.
