Last night we went out in the wife's car (corsa) and did the same section of road, the radio was fine.
Tried this Diag again this morning in the Civic, as this is when I get a very poor reception.
(Outside temp 14C car still set to 21C, rear heater off and Auto Lights on)
Radio still tuned to Radio 2 and 89.5FM signal at 65db at home on the drive.
Started driving and within 5 minutes the signal was up and down between 46 and 68db. I was hoping it would be lower with the poor sound qulity, but it wasn't. In fact the STEREO flashed at about 55db and sound quilty was poor. This seems strange to me as 55 is a highish reading.......? The RDS did it's bit as I moved from one frequency to another, but this morning had issues with all three bands (89.5, 89.1 and 89.8FM) at one point changing between all three within 10 seconds.
This all seems very odd. These highish readings in the afternoon are fine, but in the morning gives poor sound? Is something else upsetting the radio in the morning? I thought it was the rear heater, but the dew didn't clear so it wasn't on. Is it something to do with the
HID lights?
I have the questions, but not many answers.
Maybe Honda and the makers of the stereo are the only people that could solve this issue. BUT I wish they would hurry up
