Half din height FM tuner?

[sadako]

This might be off-topic but possibly related as there are DIN sized satnav units out there, although the DIN unit in question I am using is not a satnav. I wish to replace a radio in a car with a DIN sized unit. The car was originally designed for double din and has a pocket under the radio, but double din is still smaller than 2 din units next to each other so I cannot relocate the radio there.

Does anyone know if there is a slim, or half DIN FM tuner suitable for a car available anywhere? So far all my searches turn up half din EQs or DVD players...
