If your unit does not disconnect in MSM either with or without a card inserted i would be contacting garmin support for their opinion. Maybe try on other PCs/OSs first and reload the firmware first.
Sure, upload them to zippy or somewhere private and send me the link by PM or remove your UID and codes then you can safely attach them by posting in this thread.I can send you both xml files by mail if you are interested to compare. The SD xml is much smaller that unit xml.
If I remove xml from the card GE did not detect the card, but use it for map installation.
You may have misunderstood what I asked about the PC behavour, I wasn't meaning for GE but for the behavour in Windows Explorer generally. Also, did you see any differences in the card's xml before and after it's used in the unit is what i meant, not in differences between the unit & card xml files if you seemed to think. I was interested if the unit is writing to the Card's xml as it writes to the on-board xml.
