## Questions & Answers

**Q: Is this plate compatible with a TomTom rider 550 motorcycle specific gps?**
A: This ball is universal and whatever the ball size of your gps holder need to match up to same ball sizes

**Q: How tall is it?**
A: Drawing indicates 1.49" or 1 1/2" practically

**Q: Can someone share with me an amazon link for purchasing the bolts and nuts i’d need to connect this base to a garmin amps mount ?**
A: Do not have an Amazon Link but your local hardware store should stock the nuts and screws for mounting this.  They are 6-32 X 1/2 inch if I remember correctly.  Many RAM Mounts also come with a selection of the required screws.

**Q: Any chance this will mount up to a proclips phone holder for my nexus 6p?   Trying to adapt to ram mount stuff so i dont have to use proclip dashmount**
A: Richard: The key is the ball size, and also, the mount hole location in the Ram Base Unit you are referring to. Not knowing what a Proclips Phone Holder is in regard to ball size and mount holes location, I really cannot say. However, if the mount holes do not line up, you can always redrill holes in the proper location to fit the Proclips. Or, you could clue the Ram Mount to the Proclips. I went to Amazon and looked at pictures of Pro Clip Phone Holders, but I cannot tell from the picture whether the Ram Mount Base is adaptable or not, nor can I really tell exactly what kind of mount combination you have in mind. Perhaps if you could explain a little more what your intentions are, then I could offer more help..........SHALOM......Brother Randahl
