Hi, I'm having some pretty major problems trying to tranfer maps from City Nav NT 8 to my 60Csx over USB.
Waypoints transfer ok. I figure that's because it's such a small amount of data. If I transfer 1 map, it may fail, it may complete but contain corrupted data, or it may complete successfully. If I try to transfer more than one map, it will always fail.
When it fails, here are some of the ways I've seen it fail:
The transfer will stop part way through saying the device disconnected. This is how it normally fails.
The transfer may complete at the computer end but the 60Csx still sits at the "Transferring Data" screen.
The transfer may complete at the computer and appear to complete at the 60Csx, but the unit didn't reboot automatically and a manual reboot shows no map data was transferred.
The transfer may complete at the computer and appear to complete normally on the 60Csx (including reboot) but the data is corrupt meaning not all street data shows and any routing attempts will fail.
Sometimes when the transfer fails it messes up the memory card and the 60Csx won't even boot up anymore. A quick card format in my digital camera will solve this and let me boot again.
It took me about an hour yesterday to get one map seemingly successfully transferred.
I have logged a support request at Garmin but so far no response.
This is driving me crazy. I'm using all the latest versions of software, usb drivers and firmware under Windows XP SP2. I've tried the original 64 meg memory card and a 2 gig Kingston card and they both have the same results. I might try picking up a card reader on the way home and see if I can transfer maps onto the memory card directly without going through the GPSr.
Has anyone seen problems like this transferring map data? Since I haven't seen any other problems with my GPSr, I'm wondering if it's a software issue or if there could be some bigger problem with my gps unit.
Thanks...
