I'm using an iCarPlay Wireless with an iPod nano and I'm not getting any audio.
This issue should be resolved by resetting your iPod nano. Press and hold the Menu and Select buttons until the Apple logo appears, about 6 to 10 seconds. You may need to repeat this step.
My cigarette lighter connection does not turn off with the ignition. Will leaving my FM transmitter plugged-in drain my battery?
Power draw is minimal. It would take several weeks to drain your battery.
What is the difference between the iCarPlay Wireless and the iCarPlay Wireless Plus?
The iCarPlay Wireless Plus gives you the ability to program it to any frequency. Excluding 87.7MHz and 87.9MHz. iCarPlay Wireless is preset to 8 stations only. If you live in a metro area the iCarPlay Wireless Plus is recommended.
