I have an '03 plate 1.9 diesel estate Fabia, both the Radio and Cigarette Lighter (which I use for sat-nav charging) are not working. The Radio has worked intermittently for the last year, hasn't worked at all for the last 4 months. And the last time I used the lighter was 4/5 months ago, only noticed an issue recently due to needing the SatNav. I have changed both the fuses, they still do not work, Has anyone experienced anything similar/ have any advice? Much Appreciated.
