Thanks, the garmin has accepted this.
But...the junction view is not working. (full screen or split screen)
I have tried both jvc files so the small and big one.

What I have done:
Garmin 3760 EU flashed with nuvi34xx_GCDFile__760.gcd file
With garmin express updateted to 8.1
updated with Convert37x34v.zip with 8.1 Ldr.bin
JVC folder from .system deleted
mad MAP folder on SD card and insert CN NT 2014.20 EU and gmap3D.img
made JVC folder on sd card ( /Garmin/JVC )
Put in here the JVC files

Is there an idee how to get this working?

Thanks.
Br, John
