Hello AVL, in first I would try another SD Card! The best Card for flashing the device should be an 'old one' with at least 128MB/512MB!

Another way would be to try another Cardreader. Important is that you should first copy the.bin file to the SD and then after the transfer is complete copy the.cks file! I use 256Mb card includet with GPS navigator. When i go in the meny 'Other Tools' - '1= Memory Test', test not work. I see string on LCD - 'Starting address test' and that is all:( This is not normal?

May-by my memory is wrong? Hello AVL, you should use a sd card as small as possible. In my case i use a card mmc 32MB ( Nokia handy ). Even if the card works in the navi propably there might be difficulties when you use this card for flashing the rom. So if you have a smaller card (max 128MB) you should try this again with the small card.

Please copy the two files in turn one after the other and then it should go. I do not think your memory is broken, because your navi runs propably before you tried to flash. Danke, SkyHammEr.

Today i use card by 128 and 16!!! 128Mb my devise not see (say can not find WINCEIMG.CKS) 16MB - Cheksum Error. Before my experiment with WINCE updait, my GPS navigator work wery-wery bad.
