Default GPS help plz..

GPS always been working fine, I use "device only" mainly for G Maps.

Today suddenly G Maps can't locate me, just keeps saying "Waiting for location..."

Downloaded GPS Fix app from G Play Store. App instantly locates me so GPS function is available but not in G Maps, nor Yelp or Weather Channel (apps I've tried so far.)

Always worked fine before. No changes. Was working earlier today. No updates or new apps, settings, etc. All same.

Have powered off and on various times. Cleared all G Maps cache and data. Uninstalled and reinstalled. All the basic stuff, etc.

WTH?!

Running KK 4.4.2 rooted courtesey CWM etc.

Please help - thanks!
