Can I use other mounts besides MountechUSA for the Dash Mount?

Yes, you can use other mounts besides MountechUSA . You can use any 2-bolt or 4-bolt AMPS compatible ball mounts. Our MountechUSA device holders are all B-Sized compatible, so any 1" or 25.4mm ball will interface with our arm sockets and balls. Additionally, our slots on the dash mounts are 1/4", so keep that in mind when selecting hardware.
