MyFi remote control has stopped working

I had the same problem. This procedure from the "Technical Questions" section of http://shopdelphi.com/consumers/support/faqs/myfi/ worked for me:
"My MyFi won't power up, how do I reset it?
To reset your MyFi, start by turning the receiver off and removing it from its (car, home, audio system) cradle. Then remove the back cover and battery. Using a small paperclip, press the reset button located on the top left corner of the battery compartment. Now plug the AC power adapter into a wall outlet and plug the power port directly into the bottom of the MyFi (battery stays removed). Wait 10 seconds and listen for a beep. After you hear the beep the message "insert battery" will appear. Cycle the MyFi to ensure it powers up and powers down. If the power cycle is normal, then turn off the MyFi, unplug the power adapter, and reinstall the battery. Re-plug the AC power adapter directly into the bottom of the MyFi. Wait 10 seconds and listen for a beep. After the beep you will see the message "battery charging". Leave the MyFi plugged in until it's fully charged. You will see the message "charging complete" displayed. After the MyFi is fully charged, turn it on and reset to the factory defaults. Unplug the MyFi from the AC power adapter and using the battery power leave it on until it fully discharges (approximately 2-5 hours). Plug the MyFi in using the AC power adapter to recharge the unit and resume normal use. If you need help at any point during this process contact us at 1-877-463-3574 for technical support."

I hope it works for you too.

You should: Insert your MyFi into its home stand and plug the AC adapter into the wall to charge the battery.But if its really not charging a battery replacement is already needed for this unit and you can get the battery from a authorize service center.

IF you take it out of the home dock and run it on batteries, I'll bet you it works again. The newer home docks TURN OFF the FM transmitter. Try a car dock, or try it with just the power plug plugged into the bottom of the MyFi, without the home dock and see if you can now get the FM transmitter to work. Let me know. Thanks and good luck.

Pull the MyFi from the base and plug the power cable directly into the bottom of the SkyFi radio - you should be able to power up with it plugged in directly, even without any battery. Give it a try and let me know.

Very common -happened to me; cheaper to use a remote control than to get it fixed, or even buy a next generation radio.

Make sure that this is NOT a "Sure Connect" version that has a very weak FM transmitter, but the older original model with a bland box. Make sure no earphone is plugged-in, then go to the menu and set the FM frequency and set the FM output level and you should be all set..

ok i had the same problem with mine it was the power supply but i had mine in the house with the home kit hope this helps

try doing away with the external fm transmitter and use the one thats built in to the delphi you just go into settings and set it to a station that has no channels and tune it in

I have the same problem. I finally was able to get Delphi Tech Service and found out that these units have a flaw. they have been going out after about 14-18 months and there is no known repair... neither does Delphi offer a repair service for this problem.

I get the same problem once in a while. Try removing the back cover and hitting the reset button via a paper clip--then try accessing the stored content. The MyFi should "release" the stored content.
