I want to disable the $GPGSV sentences on u-Blox NEO-7M because I have serial buffer overflow on Arduino.
I found in the Receiver Discription p.69 and tried sending this:
$PUBX,40,GSV,0,0,0,0,0,0*59
But the receiver keeps sending the $GPGSV.

Without knowing much about how you're dealing with the incoming data, but if it's overflowing then its probably because the previous/current data is or has not been dealt with in a timely fashion.
With ublox7's; NEMA sentences are enabled via:
and disabled via:
You have 6 variables after the msgType whereas only 4 are expected. Other modules may require 6.
Checksum is calculated by XOR'ing all characters between the $ and the *, and is a 2 char HEX value.
eg;
and to put this in to something [re]usable:
and then to disable a message:
to enable a message:
Hope this helps.
