Traffic service on go520 using iPhone SE on bluetooth
I have go520 and iphone SE. Traffic service worked fine for years via bluetooth now it only works over wifi without using phone. I have followed all available advice on resetting go520, delete and reload mydrive and forgetting and reconnecting through blue tooth. I have succeeded in making traffic service work through bluetooth connection several times but the connection is not robust. I always end up back in the same place where phone tells me it has 2 connections on bluetooth to tomtom but tomtom tells me that data is "connecting". I know about the the work around to use phone hotspot to provide wifi connection but on a long journey this makes the phone run hot and it should and did work over bluetooth reliably. Any advice gratefully received. By the way I am live support chat having posed that question 30 minutes ago, I started at position 1 and I am still at position 1!
