Got fed up of listening to 5live on AM, and I like 6music. Bought a cheap one with a broken power socket for £25 but had to spend another £15 on an aerial adaptor and 50p on a new socket. They come up on eBay when people upgrade their cars from time to time so maybe set up a search alert. Goes to a spare FM button or the Aux.
Biggest problem I have is finding a good place for it and the wires, currently have it stuck in front of the hazzard light switch. Quite tempted to drill a hole for the wiring, as I can always stick an air freshener over the hole when I sell the car eventually.
Podcasts or iPlayer radio downloads sent to a bluetooth>FM adaptor are the cheap/easy way to get better things to listen to on the cheap.
