Trusted Reviews have published a review of the Moosik CK3000-HD unit which is a FM transmitter designed for your iPod. 'There are only four buttons and an LCD display on the device, and operation could hardly be simpler. Pressing M and then the up and down arrows lets you move between frequencies in increments of 0.1MHz. Once you find one that seems free of any station, you simply press M again and it is stored in one of five memory presets. You repeat the process again to fill up each preset. If you then use match the presets on your car radio to the same frequencies, switching between them becomes a quick two button job. The hardest part is actually finding suitable area of the FM frequency that isn’t too crowded, particularly if you in an area with lots of local or pirate ratio stations. You turn if off by pressing the power switch or just pulling it out.'
