Universal Double-DIN Trim Ring

The Metra 99-9999 kit provides a universal ISO trim ring designed to finish a double-DIN radio installation. It suits installers who need a clean dashboard appearance after fitting an aftermarket head unit. The black finish matches standard interior trim for a factory look.

Scored For Custom Fit

The trim ring features a scored back surface that allows easy trimming to match specific dash openings. This design helps achieve a precise fit without requiring specialised cutting tools. The kit contains no moving parts, so it adds no noise or power draw to the vehicle electrical system.

Mounts Two ISO Stacked Units

The kit accommodates two ISO-stacked radios held together by ISO brackets or original factory brackets. It frees the installer from fabricating custom filler panels to cover gaps around the head unit. Buyers needing a single-DIN opening or a vehicle-specific dash kit will require a different product.

Questions about this item

How do I trim the Metra 99-9999 ring to fit my dashboard opening?

Score lines on the back of the trim ring let you cut it to match the dash aperture; use a sharp knife and test-fit before final mounting.

Will the black finish on the 99-9999 trim ring fade or need refinishing over time?

The moulded black plastic is coloured throughout, so surface scratches stay inconspicuous and no refinishing is required.

What stops the double-DIN radio from rattling inside the 99-9999 kit during long drives?

A snug friction fit between the radio chassis, the ISO brackets and the scored trim ring holds the assembly rigid without separate clips.
