Check which language "Speech Recognition Data, xxxxxx ASR" you want to install.
If you choose english only, now in the .System\ASR\ folder you have two files named "en_US.srd" and "en_GB.srd".
Now copy in .System\ASR\ folder, the rest of the "special for the 3490" files depending if you have Europe or North America CN.

For 3760-->3490, you don't delete anything because you didin't have any ASR folder in the device.

Thanks let me update and see if it works ...
Awesome now it works perfectly!

Major help needed.

I finally got the courage to flash the garmin 3790t and convert it to 3490t. Followed tutorials to the letter. Firmware flashing achived BUT the flashing the 3490t splash screen was inconclusive. I decided to keep the 3490t firmware installed but wanted to restore the 3790t splash screen.

When i attempted that major fail was the result. The firmware installation halted and froze. All i have is a black screen on the 3790t. Super dissapointed.

Why you didn't read what Neil wrote to you :"you really should not attempt this at all"

Logo gone when 37xx go to 34xx because of different size of logo.
If you run on 34xx firmware then you need 34xx Logo to be flashed not 37xx logo.bin
The black screen is not the sign of dead 37xx. If you see the light appear on screen after you press power button so it means you can access preboot mode to go back to 37xx firmware.

Aekhong, you have those wings on your avatar for a reason. lol thanks for the words of encouragement. After numerous attempts< i was able to revert and flash back to 3790t firmware. :0) Thought I had a paperweight for a second. When I flashed the 3490t firmware I noticed bugs.

One bug- there is an obvious lag on junction picture pop up when the anouncement is made. The junction view picture will show up two or 3 seconds after the Jill's announcement. I've always had it in sync before. This is the large full screen JCV.

Second bug- The 3490t splash screen (1st post) has issues. When you apply it - it appears correct in the beginning but then it shifts to the top right. This was one of the reasons I wanted to revert to a 3790t splash screens. Then i got stuck for a while on the black screen of death.

Just thought I'd comment on my venture. It indeed ended well. I almost gave up. lol

I am experiencing the same issue with Garmin screen. It moves in up-right position during boot and from bottom-to up when inserting USB (white rectangle has a splitted view for few seconds). My gut feeling is that logo splash screen doesn't have the proper resolution. I'd like to know if this problem is common to everyone.

Regards, Rodrigo
