Review: Secure and stable satnav mount for ducato - Good quality and value for money. Easily installed. Very stable once fitted and keeps secure during use.
Review: Verys Satnav ram mounting system - It mated to other 25mm RAM adaptors quite well. No issues fitting my TomTom charger/docking mount to the handlebars of my Versy 1000. My TomTom Rider now sits up higher and is better positioned compared with the OEM Kawasaki SatNav mounting bracket.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Secure and stable satnav mount for ducato
*by G***. on 12 November 2025*

Good quality and value for money. Easily installed. Very stable once fitted and keeps secure during use.

### ⭐⭐⭐⭐⭐ Verys Satnav ram mounting system
*by S***R on 20 December 2020*

It mated to other 25mm RAM adaptors quite well. No issues fitting my TomTom charger/docking mount to the handlebars of my Versy 1000. My TomTom Rider now sits up higher and is better positioned compared with the OEM Kawasaki SatNav mounting bracket.

### ⭐⭐⭐⭐ Very sturdy
*by A***R on 18 March 2014*

Very strong and can be adjusted to a variety of positions. Whole system is a bit on the bulky side compared to more simple mounts. I have this in a Land Rover and it does not look out of place.
