## Questions & Answers

**Q: Can the faceplate be turned round ninety degrees? I have a Magene radar/light which uses the same quarter turn fit but is perpendicular to the Garmin.**
A: No it will not fit unless you buy an adapter like Wahoo ELEMNT Quarter Turn Mount Adapter from the likes of sigma sports £11

**Q: What's the distance between screw holes?**
A: It’s 20mm, well recommended

**Q: Can this be used on d-shape saddle post?**
A: If you mean the Giant D fuse then yes. There are a couple of rubber washers that come with it that enable a tight fit.
