GPS gone to hell with 10.10

Settings: GPS + Glonass
CPE: Current.

Before 10.10 when leaving my house for a run it would take a minute or two to get GPS lock and the tracking was close to the route I run. Since 10.10 it takes 5 to 10 minutes to get a lock and the tracking is completely screwed. And yes, I have both soft and hard reset. Map data is up to date and I sync with connect before heading out.
