how to upgrade the NAV600 to a NAV900.

[tucpal]

hi chawks i did just read your post but it seems to have gone when i approved it
can you repost if you are still having problems
ok problem solved please write in correct colors haha

also the navi 900 SD card will do nothing for the voice control function
the navi 600 does not have the software for that function to work even with the navi 900 sd card
inserting another navi SD card should not reflash it to a 600 at all
you should only need to use the USB for a reflash and it should go to 100%
can you check the map options settings on the navi and look for 3d maps first

you may need a better quality usb stick and was it blank before you put the software on it
