Morning all, been having a look through forums - and now getting myself very confused at what to do. I don't think it's a hard question - I just know little about car audio systems. We have a Mk2 Octavia with the Bolero head unit - with CD changer. I have the Octavia model without arm rest - so there's not AUX input hidden away. Basically I want to install an aux connection - ideally mounting a female 3.5mm port into one of the blanks underneath the climate controls - so we can just run a male-male lead from a phone to play spotify etc. Can somebody point me in the direction of instructions on how to connect the socket into the back of the head unit please. Then I think I need to get somebody to recode the stereo - is that correct? I haven't actually removed the head unit to check the model number - but it looks like this type, that has the SD card slot in the middle at the bottom: https://www.ebay.co.uk/itm/SKODA-YETI-OKTAVIA-BOLERO-RADIO-STEREO-HEAD-UNIT-CODE-INCLUDED/184394619712?hash=item2aeec69b40:g:Ky4AAOSwULNfLxF6 Any help much appreciated thanks.
