Radio and Nav locks up
 

Anyone have issues with the touch screen Radio/Nav locking up. Mine has done this 4 times now 3 on the radio setting where the sound will go away and nothing will work. You cant change screens or anything. Turning the truck off will reset it and then its fine. Last Friday it locked up when I was on the phone I had to change my phone to speaker to continue the call, but this time the unit stayed on when I shut the truck off. I had to pull the fuse to reset the unit. Any ideas. FYI I have had it at the dealer and they need to duplicate to fix. My 4 vidios of the unit not working I guess are not enough.

there is a CD update the dealer has. Some (blakes dad got one) recieved them in the mail. Tell the dealer you want the update. It depends on what head unit you have as there are 2 CD's for the different models. I am surprised that the dealer did not know about this or even think about it but never know with some.

Thank you. I will print this and take it to the dealer today

I have the navigation on my truck and the radio would lock up from the bluetooth. update was tried but failed. Got a new radio last week.

Does anyone know if the update can be done without my removing the "lockpic" I've installed?

Larry

Per Coastal e Techs site, the installation of the lockpic shouldn't hinder any updates.

Also, anyone wanting to skip going to the dealer for updates, when I was researching the Mygig purchase for my '08 MC before I traded it in, I found the following website which may be of interest to you: http://mofv.com/MyGIG/
