I have a  2009 Bolero unit that wont accept SD cards - it simply comes up with errors.  They are formatted correctly.

How are you formatting them - FAT32?

yes

 

Sounds like either the card reader itself is faulty (assuming you've tried your SD cards in a working unit) or the software in the unit isn't functioning correctly with the data it's receiving.

is there anyway of upgrading the software

 

Not on the Bolero that I'm aware of.

 

Ill try card reader cleaning kit - if it works Ill post so others benefit.. Cheers

Also - are you using standard SD card - and NOT the one with the micro SD in an adapter card?

I use a micro SD card (actually a 200GB micro SDXC card) in an adapter and don't have any problems, so for me this isn't an issue.

You got a good one there - they have thrown up problems for some people. Myself included!  Tried a selection of them at first - then saw a comment somewhere on here about it. Changed to standard and no probs since. The issue there is the micro card’s connection with the adapter card  becomes intermittent. Car vibration exacerbates the problem. 

 

Had fun and games with my own in the beginning.  File cleaning after saving from a Mac  was another, and max file count in the root directory (sometime a prob if >1000) . 

 

Just  to throw more  possibilities into the mix !!
