Specifications: Total cable length is 6ft with possible cable extension - Black iPod cable - Adapter weight 4 oz. Compatible with certain cars equipped with single DIN car stereo (i.e. stereo about two inches / 5 cm in height), namely: Volkswagen 98-06, Audi 98-05, Audi A3 / A4 05-06 (without satellite installed), Seat 98-08, Skoda 98-08. We also have adapters for cars equipped with double DIN stereo (i.e. stereo about four inches / 10 cm in height). They can be found at Amazon using the following SKUs for the search: GROM-I-VAG-VAGD and GROM-IW-VAG-VAGD. Special note for AUDI: In some AUDI vehicles, a solid 3-in-1 factory connector blocks access to the CD changer port. The factory connector must be removed to gain access to the CD changer port. If that is your case, you need to use AUDS harness (sold separately at Amazon, SKU# GROM-C-AUDS) that accepts the factory connector and plugs into the radio, leaving the CD changer port open for proper use of any interface adapter or auxiliary input converter.
