Transform a Nuvi 37xx in a Nuvi 34xx for dummies

Thanks for the link. I did a live update and it fixed all my problems. So far it seems like its running smoothly on my 3790. I went out to my car to check for traffic updates and it works. Thanks everyone for your help.

@ dasbell and any other Canadian or US user:

As I understand from long research, nothing led me to conclude that in 3490 there is any difference in software or firmware between these countries. There is yes a traffic coverage service that is well covered in many US cities, but not in Canada because maybe we keep on being the leftovers of the US capitalism... lol!! Just joking here! I don't feel that way a little bit, but I do feel that Garmin is not treating its Canadian customers fairly. Or is it not Garmin's fault and we are suffering from some technological hiccup!

Hi to all of the usual Hard League Members!

I'm back after a few weeks of busyness! I took a chance to read all the threads I missed since my last visit and would like to comment about the satellite accuracy problems some encountered. My converted unit is working same way as before with an accuracy meter ranging from 5-8 metres. Recently, though, I experienced only once a wierd behaviour that I wonder if is the cause to your problems. As I was driving and a few miles away from the place I had been parked and removed the unit from the power mount, I decided to rely on the gps to provide me a quicker way to arrive to a destination I was driving to. I removed the gps from my shirt pocket (sweet fit isn't it? :-D) and tuck it into the power mount. I was moving. After around 5 minutes the unit was still searching for signal and was no less than 30 meters accurate. I had to go for a halt, remove it from power, put it in sleep mode, wake it up, power it back and the unit happily picked up all satellites and 6m accuracy in a few seconds. As usually does!

So I wonder if whenever you have the accuracy problem that is due to not starting your unit when completely immobilized?

Rebooting problem:

A couple of weeks ago I had a real problem with my unit as it was doing nicely trip routing in a sunday morning and then in the afternoon it gone crazy and systematically started rebooting itself after some 15 seconds on main screen. I was just looking at it trying to figure out "what had I done wrong?" Because I hadn't done any modifications to it since using that morning I decided to connect it to the computer and look for SW updates. Nothing. Hmmm, then decided to reinstall the sw version I have, but before I did it I thought of firstly clearing nov vol (I was going to lose data anyway).
So I cleared non vol and it stopped the rebootings. It's been working fine ever since, but what could have caused the issue? I suspect low RAM in the unit, it was almost full with so much stuff planted in it that I erased. As of now I've 1.4GB free.

Try to shutdown unit and power on again.
Or try to do a hard reset.
Hope this will help to get better signal reception.

37xx has sleep mode :Animated49:, not same as old unit that will power on from non sleep mode (like turning on the computer)

Good afternoon,
Has anybody already updated firwmare to 6.2 level?
I wonder whether the new firmware improves sensitivity and stability (less frequent jumps, hang or reboot).

Regards,
Federico

I upgraded to version 6.2 and I do not have any hangs nor reboots... but again it was working fine before after a hard reset.
A couple of icons changed, not much really. I am still waiting for the app so I can connect my BB or iphone to the Nuvi.

Hi, I have updated to 6.2. It seems more stable even if jumps are still present.

I've also noticed that speed limit indication is frequently not shown and a red circle with a cross inside is presented instead. It seems that speed limit info aren't present in the map but they are since 3760 was able to show them when driving on the same road.

Has anyone experience the same issue with speed limit?

Regards,
Rodrigo

Hi,

I'm totally new to this site and I'm trying to follow Caty's instructions (post 1) to upgrade my 3790 to 3490. Caty provides links to many needed files to download, the problem is many of those links point to wuploat.it which is asking for username/password or to turbobit.net which simply says "Our service currently unavailable in your country". I'm in US. Can somebody tell me what am I missing here and how can I download those files ?

Thank you,
Andrew
