slow GPS lock and satellite pre-cache file?

I noticed that my new 945 takes much longer to lock on to satellites, in the city with buildings than my old 935.

Also I have a widget sun/moon calc on both 935 and 945.On the 935, when I go to it it just loads the times in about a second as if the location is already cached.
But on the 945 everytime I go to the widget, it shows 'Waiting for GPS-Signal' and takes quite some time.

I was looking up on google and came across this EPO 'satellite pre-cache' file that the garmin watches with mediaTek chipset use.
Is there something similar for the sony chipset used in this? Is the delay because of that?

Any clue? Anyone from Garmin?

thanks

I got 945, but when I am doing outdoor activity it’s showing as treadmill, I rested It but remains same, it’s not catching GPS satellite, when checked the software it’s showing that CPE missing, is that the reason, what I should do to fix it.

Connect to Garmin Express or sync with your smartphone to get a CPE file.

What do you mean it's showing as treadmill when you are doing an outdoor activity?

Hi Philip, Thank you for your contribution. My CPE data is missing. I have emailed Garmin support. In the meantime I have the watch sitting on my window sill with an extended timeout and it is still not registering GPS connection. Is there another way of getting the CPE file onto the watch? At this stage Im so frustrated Im ready to return the watch. This is the 2nd one I've had. The HR did not work on the 1st one!
