Thread: Patched firmwares for JNX files

I thought at the time that someone would hack the firmware to get this option for the restriction is unreasonable. And though satellite images are nice I still prefer to have digital images of calibrated, classical topographical maps on the gps.

For example - the road - or rather bush trail - I was trying to find its intersection point with the main road: but it was obscured by trees; and for the last 20 km the satellite images were taken during the winter so there was no way to see exactly where the road travelled or intersected. But with the standard topographical map it was easy to see where it went. However only one of these maps could be put into my custom map folder and only after manipulating the tile-count etc.. Given that these maps are small scale to get any reasonable amount of data into the gps was impossible - I always ran out of legal storage space.

I patched my firmware last night and already have one custom .jnx installed. I will need learn the best way to format these files for clarity and draw order.

I connected the gps and ran the webupdater . Then I copied the gupdate.GCD to my pc; I ran the patch. After copying and renaming the patched file I unplugged the gps and restarted; the update was applied. This is an excellent development.

I purchased a key for the newest version of map2pap too so I can make jnx files without the little red square.
Here is the problem I would like to learn how to correct:

The image of a topographic map is fine at 500 metre; but it is blurry at 700; it would be nice to have it clear at the higher levels too.

Is anyone aware of a good tutorial for making multi-level jnx images?

I have screen shots of the issue but I fail to have sufficient posts here to paste links otherwise I would.

Thanks
