Here's one thing you might want to try.
Put the Pro 700 in 'lightbar' mode. Toolbox>NAV S> set drop down menu to 'lightbar' instead of 'accuguide'
What this does is essentially takes the NAV controller out of the equation. Now, watch your cross track error when you're sitting completely still. Machine doesn't even need to be running, just key on. If the cross track error jumps all over the place, the antenna is your problem. If everything is fine, you're likely looking at a NAV controller issue or, even more likely, an autosense or gray cable. With the machine set to 'lightbar', you're basically just using the display and the antenna.
