Right after startup unless it is hot outside, my unit will display "No Data" about every 10 seconds and stops playing the radio. All other features work just fine (CD, Bluetooth, AUX, USB, Phone call) I confirmed the antenna is installed, in fact when removed, the signal will grow week, static, but will still play (except for the 10 seconds as mentioned) so I do not believe it is the antenna connection. I have also held the unit out of the dash and tried to shake it to see if there was a loose connection, but it didn't alter the timing of the "No Data" message.
I suspect it is a resistor
