just tried about 8 postcodes on tomtom start 52 on one stretch of the a41 between whitchurch and newport shropshire and it did not recognise any of them

tf9 2jq
Chester Road, Hinstock TF9 2ST
Chester road,, Tern Hill, Market Drayton TF9 2JQ
Crickmerry, Market Drayton TF9 2BG
Milestone, Rosehill, Market Drayton TF9 2JF

these are just a few examples of the postcodes not being recognised by the start 52 which are all on a 3 to 5 miles stretch of one of the busy roads through shropshire the A41
