Below is the complete owner’s manual for the ’67 Sapphire V AM Radio made by Bendix for Volkswagen. Bendix produced two Sapphire V AM Radios for ’67. The first was model number 7BV. The second was model number 7BVX which had a different type of output transistor to reduce failure. This manual is for the later model and has a date code of 11-66. You will notice a W after the 7BVX on the cover page. This W designates this as a Beetle radio. Bendix used letters to represent the different face plates needed for a particular VW. The list is as follows, G- Karmann Ghia, T-Transporter and a 3 for the Type 3’s.
Inside the manual you will find a parts list, installation instructions, a diagram, an electrical schematic as well as the operating instructions. Separate from the manual is a diagram and instruction sheet for mounting the antenna. One of the common 1967 one year only parts question is what knobs are correct for this radio. Well the answer is the plastic chrome knobs, or the black rubber safety knobs are both correct. The first model 7BV had the chrome knobs and the later 7BVX had the black rubber knobs to match the other dash knobs.
You will notice the drawing of the radio on the operating instructions in this manual shows the rubber knobs. You may hear and read that early ’67’s had chrome knobs and later ’67’s had rubber knobs, but these statements aren’t true. The VW factory never installed radios. They were a dealer installed extra. This means that the dealer installed whatever radio they had in stock at the time, so an early ’67 beetle may have the later version of the radio and vice versa. After 46 years though, you may find either model radio with either set of knobs.
