If the SD card in your camera is about an inch long, that will be the right physical size, but if you mean 'size' in terms of how much you can store on it, then any size will do. So I will say you should buy a 64Gbyte card for not a lot of money, but in fact able to hold more songs than you need. You can buy SD cards anywhere like Currys, Argos etc if you prefer real shops. Online buying is cheapest, if you get free P&P, but for a few quid, who cares either way?
The subject of how to copy audio files onto an SD for the card will generate 50 pages of responses, as everyone has their favourite ways to do this, depending on the source of the music. By which I mean it could be downloaded from the Internet or "ripped" from CD.
If you have CD's, let's tackle that one first and see how you get on....
On a PC or laptop, you will need to download some free software that lets you read a CD and turns the data on it into "files" stored on the PC which can then be copied to the SD card.
I suggest getting fre:ac from here (I have reasons, including autonaming the tracks!)
As a start, download fre:ac 1.1.6 (64 bit for Windows)
Then if you get that far I'll show you what to do next!
Thank you so much for this. I will have a look at fre ac but i think it will all be too complicated for me with my techie expertise or lack of. Knowing me, i will start messing around and end up ruining my computer.
As i said to City Go Man why couldn't the car makers just have left Cassette tapes or CD Radio in cars. Yes i know things move on or we would all be driving cars like Fred Flintstone.
I dont know why i started this seeing as i drive so rarely these days and i apologise to all of you for your kind input, but i am going to stick with the radio and forget SD cards.
I will stay with what i am good at like Test Driving Cars and recommending cars and heated long johns to all my fans.
