Does anyone have details of the way this particular mount attaches to an air vent? Apparently there is a "User Guide" that comes with the mount, but I haven't found an on-line version. The illustration shows two 'prongs' that I assume slide between the slats in the vent, but how is it secured?
My car is a 2014 Kia Optima, and the GPS (new) is a GO 520. I haven't been able to use a 'Universal' vent mount in this car.
Thanks. Lionel.

I forgot how they came from the factory but I believe they have a socket where the ball from the 520 is pusher in. Look at your 520 manual to see which way the device must be held to remove/insert the ball from the magnetic holder socket. Do not take apart on a daily basis.
I had a 600 which is quite a bit heavier than your 520 and had problems holding it tight to the dashboard. The problem comes if the vent slats are relatively thin. As you can see from the picture below, when the tips are tight there is quite an air gap at the heel of the mount.
I tested pre production models and recommended not to have radius in the back as all cars have different dashes.
The fingers seen are tightened by rotating the grip, same as with the current suction devices.

Push the fingers all the way for ward then rotate the grip to clamp.
If the slat is relatively thin the tips will clamp but with bumps on the road the device has a tendency to wiggle left right, but not fall off. If it wiggles, the tips are so tight that the holder cannot be pushed forward without first loosening the rotary lock.
If it is like that, either but some resilient material on the fingers or put a piece of foam on the sides of the curved back.
In spite of the above, quite a few people like using it.
You may not need it with the redesigned magnetic mounts of the 520/620 but on my 600 I had to hold the bracket with one hand while removing the device.

If the above does not apply to you, take a picture of your mount and attach it with your reply.

Thank you for your detailed explanation. I now think this vent mount may be usable, but it is expensive here in AU. Still considering!
I have not (yet) purchased the vent mount, the 520 was supplied with a suction mount. From the illustration, the vent mount includes the magnetic holder, so it is not necessary to remove the ball.

Is it illegal to have the suction mount on a spot it would be convenient.
Ever since I got my 620 the suction mount has not been removed for the windshield which is almost a year now.
In my opinion the current magnetic mount is the best TomTom has ever made.

I cannot tell from the picture but it looks as if they followed my advice and had the mould changed, giving it a flat back, albeit angled. If yes, that would eliminate the left/right wiggling I mentioned and it would have taken a skilled mould maker less than one hour to finish changing a single cavity.

If you buy one, do not unscrew the finger opening until it comes apart internally as a snap ring willl fall off a pin inside and you have to take the whole thing apart, to reassemble it properly again.

Thanks for your interest. I don't plan to purchase the vent mount, as I don't think there is sufficient room between the steering column control stalks and the adjacent vents. The other vent is too far away. I'll continue to use the windscreen suction mount.
Different topic - transferring the My Places I have stored on my old GO 5100 to the GO 520. I've searched but haven't found a workable method yet. Any pointers will be deeply appreciated!
