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

@Catmag:



Is that the only I needed since my device is 3450? So I would flash full 37xx firmware from the pic attach, not 34xx?

yes it's that one, flash 37xx firmware than use this file in sd

Is this how it is? Sorry, I just want to be sure I'm doing correctly. Do I need to remove GUPDATE.gcd for flashing 37xx firmware?
As the picture stated. 1st flash "nuvi37xx_GCDFile__450.rgn" then flash convert37x34 from SD card. From here, do I select 34xx or 37xx if asked?

Thank you very much Catmag for all your help and not giving up on me.

point 1: yes
point2: there is just one file that work with both firmwares, use it like it is, unpack and copy in sd

@Catmag: ok I did do the 37xx flash and then the convert37x34 from SD card. But this give me the 37xx nuvi not 3450. When i flash the 34xx firmware, it give enable all feature. I still can't disable those extra feature and I can't return to Garmin when the look on the screen is 37xx or 34xx with all feature enabled.

so i try copy these file to Garmin folder, restart, but no luck in disable those extra feature

What do you have in Setting/Info/About?
Send it to Garmin, your nuvi has too many problems, probably that update damaged nuvi nv.
We could try to restore nv , but I guess you dont have nv backup.

Unfortunately no i do not have nv backp since i never thought that the webUpdater cause a problem. Setting--info--about--is 3450 and everything r the same bsides those extra feature that only 3490 would have, not 3450. So, What's my excuse of telling nuvi when they see those extra feature, bluetooth, voice command, etc?

They will send you a refurbished one, np. You have those dots line on screen and this is enough to see Nuvi doesnt work fine.

So i guess b4 sending it back, I need to paste the original LEX_PGK, delete CXNA, POI, delete all .unl i created etc..

again thanks for all the help. plus i don't think they send me a refurbished since mind only been 2wks. Garmin rep gave me her personal work email so that communication r ez, instead of going to various rep. i already email her the picture of those dot. her reply when she saw the pic

Thank you for the reply. The pictures seem to make the marks look almost like a fine crac.k. Are you able to see the markings when the unit is off too? Does the display have any distortion or discoloration?

my reply

it's not a crac.k. The screen is smooth when feeling it. No distortion nor discoloration. When it's off I hardly see it since the screen is dark. When it's on yes I can see the dot as in the pictures. However, that dot thing, sometime I see it. For instead, last night at home I saw it and able to took pic for you. And now as I'm emailing you, I can't see it. But earlier today, I saw it.

Another thing was before the v7.10 update, my PC, Windows 7, able to find nuvi right away, in a second. Now, it took about a min or so. Plus some time it asks me to scan the nuvi.

Thanks,

Good reply, yes try to remove everything you havent got from Garmin, unlocked maps ,cyclops etc
As I know,Garmin always replaces non working devices with refurbished ones.
