Hello,

No answer :(

Is there somebody with a Vista Cx in this room ?

Could he tell me his values for acquisition time with his vista Cx ?

This is what I have now that I collected almanac :

* cold start :
Vista C = 40s
Vista Cx = 80s

* warm start :
Vista C = 10s
Vista Cx = 50s

Thanks !

My Vista Cx's acquisition time is MUCH better than my iQue 3600 and
somewhat better than the values shown in previous posts:

Warm start: 20 seconds
Cold Start: 45 seconds

to full lock (with WAAS enabled)

Cas.
