I purchased a new cateye astrayle? Heres the problem: when riding, everything looking good (also happens right out of the shoot) the readout drops to zero, as if there is no connection. So I sit there moving the unit in its base - finally it connects to the leads and the readout comes back on. The problem is the connection between the unit and the base its clicked into. Has anyone else had this problem, seems rather lame to have to adjust after every bump!
