I have a fiat panda 100hp -2007 need a stereo that has USB and an aux lead, looking at Halfords cheapest option I will be paying over £130 which is ridiculous, anyone changed it them selfs with an ebay buy? How easy was it to do? Any recommendations of good double din radios would be appreciated

fit by yourself, you can find the tips on this site:
