I have a V3 RAZR and the RAZR Cradle for my 08 E550.

Everything worked flawlessly until today. Went to check voicemail while driving, used the keypad on COMAND to put in my PIN and as soon as I hit the first digit, the tone just stayed and got stuck until I hung up the call.

Thought this was strange since it didnt do this before, so I rebooted my phone, and the COMAND system. Didn't fix the issue.

Waited until I could stop the car, shut it off, turned it back on, no luck.

Went into the phone's menu and set DTMF from "long" to "short" tones.

No luck.

I'm of course going to try a "master reset" on my phone and re-pair it, but something is obviously strange since everything worked flawlessly for about a week. I did just get the car back from service yesterday where they changed two blown bulbs.

Anyone else experience this?

 

I had this happen on a V60 bluetooth module a few times. To reset , had to pull the bluetooth puck and allow to reboot. It seems it you deliberatly hold the dtmf keys for a second to avoid switch bounce the problem does not happen.

 

I just went to bed, woke up, tried it again and now it works like normal.

Strange because half a dozen reboots of the COMAND system didnt help.
