our street pilot with an ext ant would not work in the SVX. I tried it in SickSubie's, the only way to get a signal was to put it all the way to the pillar. I think it was the first time I used it in an SVX, so it shouldn't have just been a fluke.
I would go the external ant idea if it is also a remote one (like with a cord), my external ant for gps is on the the turnk. I have one for gps and one for xm on opposite sides, looks like hinges until you see the little xm logo on one
