Sat Nav Holder

[Suetheramble]

Just purchased a sta nav holder from Amazon a:-

Garmin Nuvi 370 ,360 ,350 ,310 ,300 Series Suction Cup Mount

It has arrived as 2 separate parts.
How does the "ball" part fit into the smaller square holder that attaches to the sat nav?

It a kind of push and screw movement



Now waits for the usual suspects to appear lol

Bingo!
Push and screw + Brute force and ognorance.

Thank you
