Hi I posted this also to alt.satellite.gps.garmin but thought I'd see if any of you folks can help. I have a streetpilot 2610 which appears to have maps on it of UK - shows town names etc but doesn't show minor roads. I have mapsource (v6.9.1) on the laptop and I can mark a section of map for transfer - when I send it, it almost completes then displays and error in mapsource "the gps has returned an error status while receiving data packets." The strange thing is that sometimes the map detail DOES appear to have been sent (for just one area) but the next time I try to send it or any others, it gets removed. The way the unit is now with its data is inadequate for any detailed route planning though will at least show me where I am to towns etc and does show as I said the major roads. As far as I can tell there are only 2 small areas of UK maps installed on the Streetpilot at the moment. I have also reinstalled mapsource City Navigator Europe 7 and tried it and then tried it after installing City Navigator Europe 8. Appreciate any tips. Is there a way I can reformat the memory card (it is a 2gb that was supplied with the unit when I bought it off ebay earlier this year) or does that risk losing ALL the maps installed? I wondered if it was a capacity problem, the message doesn't indicate that but I am also unaware of how to extsblish the capacity of the memory card.
