Carplay cuts out my car radio when using maps
Hi ever since updating to iOS 10.3.2 whenever I connect my iPhone 6 it cuts out my car radio after a couple of minutes. This is quite annoying as it didn't happen before the update, I could use maps and listen to local radio at the same time. Any ideas for a fix? By the way I have tried my daughters iPhone 5s which hasn't been updated and there are no problems at all. Thanks!
iPhone 6, iOS 10.3.2
