Lost ipod nano in a taxi going from Walkinstown to Clarehall

Hi I lost a an ipod nano in a taxi going from Walkinstown to Clarehall early Sunday morning 8th July. i got out in Phibsboro, my mate got dropped to Clarehall. Its the plain ipod colour (grey/black) and I was sitting in the back of the taxi. The stops along the way were Drimnagh, Thomas St, Phibsboro and then Clarehall in case the taxi man still has it. If you dropped it in to a Garda station can you let me know which one. Thanks!
