Aaargghh!
Just discovered the switch is broken off my tracker! And its out of warranty too.
Managed to switch it on using screw driver to move mechanism but concerned that the electronics are exposed by the hole where the switch was. Could glue it back and seal round it then use the batterys as for on/off.
Am I kidding myself or is it destined for landfill. Think I know the answer but needed to share my pain!
