As Satmap has gone under I thought I would "upgrade" to Garmin with OS Mapping SD card.
Bought from Ordnance Survey Shop and arrived today. Turned on the unit, installed the SD card and performed all updates that is required. Looked at the mapping screen and was shocked to see very poor quality rendering of the OS map, akin to very low resolution jpg is this right or have I been sold a dud? I would have expected a crisp clear map on my screen!
