I recently replaced my radio with an android unit from Amazon. Everything works nicely except for the outside temp display. The factory radio had a mini USB from the HMI 2.0 and a smaller grey plug. I'm not sure which one would've carried the info for the temp. It also seems like USB data won't travel through the HMI to the new radio. If I plug a thumb drive directly into the radio, I can see it. But if I go into a USB from the HMI I got nothing. Any kdy have any thoughts?
