Steve,

I'm still on the follwing Mapsource upload problem.

- pan and zoom: OK
- select tiles: OK
- idx creation: CRASH at ca. 14%

After some extended testing I could narrow down the problem to
only *two* tiles causing the problem and make it reproducable!
I'm using mkgmap r1949 meanwhile.

70014464.img -- XK-Pristina (according to cities15000-file)
70014652.img -- BG-Sofice

The picture is the following:

a) I can upload both tiles each individually to my GPS without problems.
b) Both tiles in combination cause the problem.

That means to me that I need to do some further investigation:

i) The problem could be caused by splitter doing some nasty things on 
both tiles in combination that makes idx creation fail.

ii) The problem could be with .img tile creation. Some idx related data 
is incompatible across the two tiles (duplicated ids, inconsistent ids, 
etc ...).

iii) The problem could be with the original OSM data that contains a 
situation that mkgmap can not handle. Anybody else experienced Mapsource 
problems in the Macedonia / Greece  (Skopje / Thessaloniki) area?

I need some hints on what and how I could proceed with my testing.
What is your opinion / your experience?

I'm sure the problem exists also with some other tile pairs. Because i 
tried to exempt the above mentioned two problematic tiles from idx 
creation and select the rest (while respecting the current 4 GB 
restrivtion in Mapsource). The upload also failed. So this means to me 
that the problem is not a singular one restricted to only the above 
mentioned tile combination.
