GM Radio 20934593 in my Tahoe 2007 USB not working

[Habnixzuverliern]

Hi,

 

as my Headline describe, I have a new Radio(GM 20934593) with USB Port in my 2007 Tahoe. I programmed this device with my VIN and my RPO Codes and the unite start working, but I cant get USB to work. I tried it with a USB Stick and my Iphone - nothing. if I switch manual to USB it said there is no USB device.

 

So I tried it with my VIN, I tried it with a 2010 and 2012 Vin, the programming give me different options, but regarding the USB Port nothing worked.

 

I read in this forum that a few people here in this forum did this swap to get USB in a 2007 Car. So I need help.

 

Can someone give me an advice what I can do or how can I program this unit.

 

Cheers

I put one in my 09 non-bose and added the factory plug and cord, but had mine programmed by the person I bought it off of so it was plug and play. Do you have any way to try with a standard mini usb cord to female usb and see if you have a bad or loose port or cable?

Hi,

 

i checked it with a second cable but nothing worked. I also tried it with different USB Sticks, nothing..... it looks like there is no power on the USB Port.

The led on the sticks are not blinking.

 

Cheers.
