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

cz9h3d · 27th July 2013, 05:27 AM

Successfully flashed and updated..... except I have the "American English" issue for voice recognition. My original unit is a 3760t. I installed the American English ASR via web updater - but looks like I'm missing a similar file(s) needed for my maps (2014.10) - I assume I likely have a similar issues for 3D, which I haven't tested yet. I'll fix this in the morning.... hopefully I don't have the accuracy issue with my unit.... I hope not - I don't want to have to flash it back

My 3760/34XX has 4GB of internal memory. Prior to reflashing it, it already had 2014.10 maps (NA map file and the junction view file from torrent). As I now wade through this thread (and others) to figure out what additional files I need to get it fully working, I'm concerned about having enough memory.

What I think I need to add:
ASR / SRX: I have the ASR folder already from using WebUpdater to add the English file. Just add the additional map-specific ASR & SRX files (which I've downloaded from the 2014.10 thread)
3D: gmap3d.img from 2014.10 goes into the hidden .System directory
SID: Multiple SID files go into this newly created folder in the .System directory
DB: Map/Unit specific D3397090A.DB goes into the existing SQlite folder

Am I missing anything? And thoughts on making it all fit? I had already pruned the voices down to just English ones. I'm sure this is a standard question/issue, so I'll do some digging around....

After 48 hours of intense reading and learning, I'll have forgotten it all within a few days....

Only 4GB on the 3760t is a pain - but I think I've managed to find/install all the supporting files for 3D and to get voice recognition working. I moved the main NA 2014.10 map file out of main memory, and it now resides on the SD card. Oh, and my onboard memory is FULL! We're talking 123MB left.
But....One little issue......

The "Find Place" command causes the unit to turn off. All other voice commands seem to be working fine. After saying "Find Place", I briefly get the next screen (blue), and sometimes I get the voice instructions to begin.
But the unit then turns off.

Any ideas? This is one of the more useful commands....

thanks...

ASR/SRX: These files are specific for your unit and to the map, so provided you've dl'ed the correct ASR'2' files to match your NA 2014.10 map they will work. You also need to have the en_US.srd in the ASR folder to go with your US TTS voice/s, and that should have been offered by WebUpdater.

3D, SID & DB: That's all correct.

Do you get a message saying this feature is not available in American English? Check the following.
Do you have the en_US.srd file in the ASR folder, and using either English_American_Jack.vpm or English_American_Jill.vpm TTS voice file? Also have you got either a complete map of US lower 49 or a complete NA? [i.e. no tiles missing, not even one].

If all seems correct as above, redownload and replace all the ASR/SRX ensuring they are the ASR'2' files for 2012> devices, not the ASR'1' 2011 files.

I recopied the ASR/SRX and SID files over to the unit. It also looks like I "missed" copying the .db file to the SQlite folder.

Now "Find Place" works perfectly..... And I'm using the Australian voices, they sound much better than the American (I think my wife has a crush on Lee).

Thanks for the help. Great thread.

I have a problem. Poi search doesn't work on converted device for me.
Every time I do "Where To / Categories / Restaurants" and search for "Starbucks" I immediately get "Cannot find search results...". I have all SID files, and it looks like address search does work. Only issues with POI.
Any ideas?

Edit:
Found it happens due to Europe DEM Layer. Anybody knows how to fix that without turning DEM Layer off?

May be don't you have proper files for 34xx? I don't think DEM can interfere with POIs search

Back again....my junction view isn't working. I had the 2014.10 maps w/Junction View working previously on my 3760 - and am using the same files on my converted 3490.

I did have to move my map file over to the SD card due to memory limitations. Initially I kept my JCV folder/file in main memory in the System/JCV folder. So I thought maybe it needed to be on the SD card too, and moved it over to a Garmin/JCV folder. Still no JCV.

What to try next???

If it's the right jcv file [D3191090A.JCV] for the NA 2014.10 map and it must be if it was working before as 3760, then there is no good reason why the exact same map & jcv file won't work with the unit converted to 3490. Those described paths are correct too for the unit and card. It doesn't matter if the jcv file and map are both on the unit or card, or one is one the card and the other on the unit. I don't know what to suggest other than are you sure you've tried a route with JC views available? Try a simulated route from the center of NY City. Select New York, NY from the top of the list [Press Where To?>Categories>Towns>Enter Search>'New York'] and then set that as your location. Then repeat for Buffalo, NY as a destination. There are heaps of JC Views on that route.

Otherwise, redownload the JCV file and replace your current copy. Maybe it's been damaged somehow.
