GPS acting up?
I got a Nexus a while back and I had it replaced within the first week since I had a dead pixel. Everything was working fine, a couple of months later I rooted and installed CyanogenMod, which was great.
A couple weeks ago I started to notice the GPS wasn't picking up the signal all the time. It worked before without any flaws but now I kept on receiving the 'Waiting for location' + 'Your location is currently unavailable' error (I turned off WiFi so I could test only the GPS).
I made sure this was done in an open environment [a moving train with open sky in all directions].
The other day I was able to get signal while sitting in a car [that wasn't moving]. I turned GPS off and back on and I wasn't able to get the signal again.
I also used to be able to get signal while sitting in the basement but nothing anymore.
Is this more than a software issue? If it could be, I plan on reverting back to the stock firmware but I don't want to go through the hassle if it wont solve the problem.
Thanks for any help.

Two things to try.
This is actually bad place to try to get an initial GPS fix. Because 1 you are moving and 2 chances are if it is an electric train with overhead power it will have a all sorts of interference between you and the sky.

This step is only necessary for getting you first fix at a location. If the GPS is already localised you should be able to get a fix in your moving train OK.
Next thing to try, is to flush the satellite ephemeris data telling the GPS where & which satellite to expect to "see" at your location at the current time. Seems to me sometimes this info can get messed up (on any gps not just the N1). I found turning off the N1 and removing the battery for 5 or 10 minutes seems to fix this. Might just be placebo but I reckon it works.
Both of these steps should be a one off. Once it is working properly again you should be able to get a fix quickly.
