Hi, I've owned an Octavia from new for about 6 months. From new, every now and again the Bolero system starts playing from the SD card for no apparent reason. This can happen when I'm driving along with or without the radio on - it's as if I have just inserted an SD card and it starts to play it automatically. It happened in the middle of the night last night and woke up my neighbours! The only solutions I can think of are either to remove the SD card when I'm not listening to it, or mute the volume so even if it does turn back on no-one will hear it.

Has anyone else had this problem, what could be causing it?

Hi, Your not the only one however, as my car has done it twice tonight, both times turning on to the SD card when I have had the radio on last time I used it.

Going to go and have a play with card in or out. Anyone any thoughts or seen this one before?

Get a Priest to have a look at it, sounds like your Bolero is haunted !

+ 1 that is downright weird!

Not quite sure I follow... are you saying the whole unit starts up and plays something from the SD card?

Or are you saying you might be driving along, listening the the radio, and suddenly the SD card is selected and starts playing?

On the second issue, I have experienced this in my Superb II with a Columbus unit. My not terribly technical diagnostics so far are as follows:

1) Media playing function will switch to the SD card if it is detected as present even though another source is selected. Unless it was originally detected at "start up" and something else was chosen, thus overriding it.

2) In cold weather, the SD card "mechanism/electronics" are a bit dodgy, and will not detect an inserted card until the unit has warmed up a bit. Here in the south east, I have been experiencing this since early November. I listen mainly from the SD card for choice, but it will not work first thing in the morning, so I have switched to Radio 4, started driving, and then after about 10 mins the SD suddenly kicks in... annoying- but as it "always" happens now (in this colder weather), at least I know the cause (well... not technically.)

3) I did try taking out the SD card at night and bringing it inside, in case it was the card itself that was "cold". I tried other cards, but it seems to be the unit reader mechanism rather than the media.

So what did I do...?

Well, (1) it prompted me to make better use of the harddisk unit (present in the Columbus), so I copied the SD card content there instead, and use that a lot more now. But obviously, if the SD card is still present, then it overrides the HDD after 10 or so mins, so (2) the SD card is always in the slot, but ejected, now. I use it every so often, and for loading the HDD, but never at the start of a journey.

Does his help explain? I realise it doesn't help much with the Bolero unit as there is no HDD I believe, but maybe you will have some luck questioning the dealer on this basis. Problem I have had, is by the time I reach the dealer the damned thing works!

Puss.

@ Briskodian : Yes the unit can be turned off but will turn itself on and start playing from the SD card. Exactly as it would if it was off and you inserted an SD card into it. It ony seems to happen with one SD card - a 32gb one. The other one I've had ( a 2gb) one doesn't seem to reproduce the fault. Your idea about the temperature is good but mine started playing in the middle of the night once and woke up my neighbours! This seems to exclude a temperature or vibration cause.

I suspect the cards are the issue, not all SD cards are the same. If the card is slightly thinner then the contact between headunit and card contacts may not be very good and this could lead to the headunit sometimes thinking the card has been removed and inserted. This would switch the headunit on if it was off, or switch source if on and listening to CD or Radio.
