Nokia :: 6303 - Map Loader Stops Halfway

For ten days I've been trying to get the maps for Europe on my 4 GB SD card. With the larger country files the DL stops between 40% and 99,3 % (Yes indeed)
There obviously is no resume function on the Nokia Server nor inside the Maps Downloader (like FTP servers do have) thus I have to start all over again. It took a lot of patience and even more luck as well. For some countries I had to retry 17 times and for about 1 GB of country files my DU-meter indicates a 5 GB DL traffic. By now I have almost all European countries except:
England 89,5 MB (Scotland, Wales and Northern Ireland are OK)
Finland (of all countries!) 91,5 MB
Poland 71,2 MB

It makes no difference whether I start downloading maps from the PC-Suite or directly under Windows XP (SP3). Two weeks ago I had the same problem with another 6303 which I returned to the webshop. The original 1 GB SD card on both models has the same download problem.
Some voice files DL's were OK. The LD-4W did find my 'Current location' and I could save. Adresses of friends in Holland and in Spain were found easily.

Data:

This 6303 runs SW v.10.10 in PC-Suite mode via USB cable.
I had NP with the SW update from v.9.10 (out of the box) to v.10.10, but v.9.10 had the same problem.
