I replaced my GPS module and I can't get any satellites now. I get the normal yellow flashing after start-up check but when I try to start the motors, I get this:

YY   RRRRR  YY  YY  YY  YY........(YY continues)

Is it a battery problem? or GPS connection problem?

Please help!

Also motors do not fire

Did you plug in the GPS to the correct plug?  It is on the back of the board above the battery insert directly to the right of the white plugs,  it is labeled in very small letters GPS.

I did, I have concerns about connection security in that socket since the plug and the socket are not a snug fit.

What was wrong with the old one?

It is a common mistake to plug it in to the wrong slot, as it will fit in to a few different spots.  I disconnected mine to shield it and plugged it back in and it refused to start.  I had it plugged into the wrong spot.  The plug and pins do connect securely.

Crashed, broke ceramic antenna, unsoldered and replaced, still no joy, bought new GPS, still no joy
