I am currently in Turkey having ridden from the UK and have been some what frustrated at the performance of the Garmin GPSMAP 60CSx. In the UK it behaved fine but in some of the large urban areas (for example Istanbul) it really chugs at certain zoom levels when trying to draw the map. This can lead to some real issues when it is taking 20 seconds or so to display what you want. In addition it just cant do routing for locations that are really far apart. It takes ages working the route out and then says its run out of memory. What are peoples experiences of this and what is it like compared to the new GPSMAP62?
