Oh no, I was speaking always of timing version GPSes. For non timing version GPSes you loose the position-hold timing mode too. uBlox has T-RAIM in the LEA6-T version. In the block diagram of uBlox GPSes they show the option XTAL/TCXO for their receivers. Although not stated, I believe that the TCXO option is reserved for the timing version hardware.
