Dewsbury CID are asking anyone who has had a sat nav stolen in Huddersfield recently to get in touch.
Officers hope to find the owner of the Tom Tom XL sat nav which was recently recovered in Mirfield.
The device had a Homer Simpson voice downloaded to it and appeared to have been used on a trip to Europe in 2011.
It is possible it was taken from the Watergate area of Huddersfield.
Anyone who has information should contact acting Det Sgt James Bellhouse at Kirklees CID on 101 or CrimeStoppers on 0800 555 111.
