I would say to perspective buyers it is great but for one problem. my hs scares the crap out of me. only due to warning triangle yellow , well m1 to Barnsley on slip road motorway m1 this yellow triangle appears. now whilst looking for it I may crash , on return to morley same motorway m1 nothing , and on occasion other roads too. SO HOW DO I TURN IT OFF BEFORE I CRASH , OR DO I ASK FOR ANOTHER IN REPLACEMENT.
