Need replacement knob for Parrot Bluetooth car kit MKi9200
Went to Radio Shack after we lost the knob to our MKi9200 and bought an Insert Control Knob. The blue one is model #274-403. It also comes in red. They are sold in a two-pack for $1.99.
To install it, first you need to file off the plastic pointer on the side of the knob so that the knob is perfectly round. There is a small screw on the side of this knob so that you can tighten the knob to the post on the remote.
Advantages of this knob over the original Parrot knob are (1) the knob _never_ falls off, and (2) there is more tactile feedback when turning the knob. I like the asthetics of the blue. The only drawback is that it is more difficult to spin the knob quickly in long lists.
