Bolero Radio

Got a Bolero radio in my Octavia and had a bury cc6090 bluetooth car kit fittied routed through the car speakers. Whether it is coincidence but 3 weeks later when starting the car over, sporadically the radio fails to come on. (radio is left on when the car is stopped and locked) It stays on if the key is postion 1/2 in ignition sequence but turns off and doen't come back on when the car is started. Only happens now and again but doesn't follow a pattern. Any ideas? Do you think the bluetooth kit has anything too do with it?
