Driving in Cornwall - Tintagel to Penzance

Hello,
Just here to provide some unsolicited advice for anyone headed to Cornwall.
The A30 between Tintagel and Penzance just finished getting redone from a two lane road with round-a-bouts to a very nice dual carriageway. Your GPS will lose her mind in the new section. Just ignore her and keep going straight. She'll get it together when you get back to the old road. I followed her the first time and ended up in a cow pasture.

Just trying to help.
Safe travels,
Victoria Dell
