I also checked on the garmin website but it's not clear at all. Can somebody help me out please?
EDIT: I found this: "Smartphone Link also enhances Garmin's standard safety camera alerts with Speedwatch data, which provides real-time updates for fixed, temporary and average speed cameras, mobile zones and red light cameras together with "crowd-sourced" mobile speed traps reported by Speedwatch customers." This basically contradicts (at least in part) what garmin wrote on the smartphone link app....this is driving me crazy!!!
