I already have a handheld GME TX6150 so I just have to get bluetooth capability with harness and mount so I can connect to my Cardo SHO-1 helmet communications set.
Spoke to these guys at Soundrider on the sunshine coast who have the harnesses available and they also have mounting kits from RAM mounts.
The plan is to have this mounted on my handlebars, not to have it charging but just mounted in a clip. The charge lasts forever in this anyway. So I just need the bluetooth connectivity and harness installed to the trike.
