I play with my nuvi 3490 and find something interesting when i try to enable active lane guidance



First i explore region 140 from nuvi 2597 from @Alviora.

I see that in region 140 is Photoreal JCV.xml enabled by default and also that reg140 on nuvi 2597 start with 28 but on 3490 start with 20, then i start testing and this is result:

First i only add 01 in place in red circle on picture below, look also at start number:

But supported_features.html is after this change like before (no change in supported_features.html )

<html><br><b>Supported Features</b><br><br>Part Number: 006-D2617-00<br>Rev: 0A<br><br>3D Buildings<br>3D Terrain<br>TTS Phonetics<br>Junction View<br>Lane Assist<br>Speed Limits<br>Traffic EULA<br>Photo Nav<br>ASR<br>Historic Traffic<br>Custom Avoidances<br>Advanced Detours<br>Premium Point Addressing<br>2D Footprints<br>3D Buildings Supplementary<br>Bluetooth<br>MP3<br>Video Playback<br></html>
Then i change in reg140 start number from 20 to 28 ( like on nuvi 2597) and add 01 in place where nuvi 2597 have enabled PhotoReal JCV.

and now supported_features.html look like this:

<html><br><b>Supported Features</b><br><br>Part Number: 006-D2617-00<br>Rev: 0A<br><br>3D Buildings<br>3D Terrain<br>TTS Phonetics<br>Junction View<br>Lane Assist<br>Speed Limits<br>Traffic EULA<br>Photo Nav<br>ASR<br>Historic Traffic<br>Custom Avoidances<br>Advanced Detours<br>Premium Point Addressing<br>2D Footprints<br>3D Buildings Supplementary<br>Bluetooth<br>MP3<br>Video Playback<br>Photo Real JCV<br></html>
So i have no luck to enable active lane guidance ( i think that nuvi series 2013 will have different JCV or this function by default in FW) but found out how to enable Photo Real JCV to show in .html

p.s.
Maybe we must also flash region 132 and 150 becouse nuvi 2597 have data in this two region, but nuvi 3490 have this region empty.
I don't know what data is in region 132 and 150 so i will not flash it on nuvi 3490. ( maybe someday when i know what is this data )
