Hi there and welcome

When the update fails, can you tell me if it gives an error message or it just disconnects?

Customer: replied 22 days ago.
Reaches 48% sometimes and just drop or hang and show downloading but not doing so. in some cases connection lost.
Expert:  Richard replied 22 days ago.


It points to either a faulty card or internal memory on the unit.

Can you get a different SD card, copy the contents to it from the other SD card and tell me if that then updates please.

Customer: replied 22 days ago.
ok will try that, the garmin unit come with a preloaded map so doesn't have space, the sd card is a new empty 8gig card, which contents are you referring to
Expert:  Richard replied 21 days ago.

Ok, if it is empty then there is no content to copy over, so try a different card please.
