i noticed today the bluetooth connection between the n800 and the ld-3w was working but the navicore software wasn't able to access the data passing to the n800. turning off the gps and the n800 and re-establishing the bluetooth connection didn't help. nor did 'reseting' the gps by holding its power switch in. taking the battery out of the n800 didn't help. finally i removed the battery from the gps module (what a hassle it is to get the lid off), counted to ten, and put the unit back together. seems to be working just fine now. any ideas what might be going on? the navicore program kept saying there was no bluetooth device available. john
