Even though this item didn't list the Tomtom XXL 530S as a compatible GPS, it was absolutely compatible. Setup was a breeze (remove the window suction attachment, use the included adaptor attachment to the back, and simply use the bottom suction and lever to secure the GPS in place). The dashboard base is SO well weighted that it didn't even need the accompanying back hook - which unfortunately didn't stick on my curved/humped Hyundai Santa Fe center dash. No issues, no falling off the stand, no sliding around. Granted I've only used it for a day, but I've seen more expensive dash mounts with horrible ratings. This one is economical, and definitely serves its purpose!
