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

Hi, after downgrading from "3490" to 3760 + 3790 extensions, the system is in a kind of mixed configuration even if I cleared non vol stats after firmware installation.
Specifically, my unit uses "3490" layout during navigation mode: blue color bar for next destination (instead of green), speed limit red circle (instead of white square). I like a lot this kind of layout and I would like to maintain it in the future.
Does anybody know where this layout configuration is stored? My idea is to back it up and reinstall in case default 3760 layout appears again in a future FW upgrade.

Regards,
Rodrigo

Hi Caty,
Have you tried Basecamp ?
The specification says Basecamp Only for 34XX (3790 V4.7 Basecamp + Mapsource)

@ caty:

Thanx for the hint and redirection. In fact I followed it and it seems to be working properly. The reason why I was having the message "voice command not available for american english" was missing files. I believe my unit is working fine now, but I'll be testing it these days (too much work is keeping me off the road :-( ) and as soon as I have some echo I'll be posting my conclusion here.

Look like this

Finally after a few days of testing I have something to share:

For all that have voice command error message - see post #212.
Solution = download files recommended in post #47 for CNE or in post #221 for CNNA users and uncompress them. Copy all files to your nuvi (*.asr to .system/ASR,, *.sid to .system/SID and *.db to .system/SQLite). Reboot, connect to pc and launch webupdater to verify if you need any new files for your nuvi to work the way you want. Enjoy!

I have one question: is there any thread where we can only read and post things related to the 37xx and 34xx user interfaces? Or is it ok if it can be done here?

Hi kaspiic,

I have HD EcoRoute too. I just put all the .xml's and execute them. After that, in the car i just connect the device to the HD EcoRoute. May be it's not the best way, but it working for me right now. May be someone will explain exactly what doing each of these .xml's.

About the traffic receiver - it works great with this firmware.

Use DeviceConfig_ecoRouteStandard_Enabled.xml, this is standard ecoRoute like in 37xx, function will work without HD but with possibility to connect HD.

updated my 3790EU to 3490 - no problems with update process. It show me that model is still 3790 - but acts and updates as 34xx.

But... i also have "jumping car" effect! In simulation!!!! (and in real world too)
especially when i zoom in to max zoom - car jumping forth - back all the time when moving!
And when destination is reached- car sometimes jumped to next street (in simulation mode!).
When i zoom out a little - car jumping stops, but i can see that map draw "jumping" a little - no smooth movement as with original FW.

I remember, that in GPS modules there is option to average GPS signal - so position not jumping all the time. in car GPS, as i know ,that option is turned on by default + when movement is less than 5 km/h - position marker don`t move (or something like that - maybe i`m wrong).

Maybe problem is there???
But car jumping in simulation mode - thats strange.....
