Hi all. Firstly, LightningUK - thank you, Img Burn is great, small simple and does the job perfectly. The interface is intuitive and requires very little to use, KUDOS.
I have a car (Honda) that has a music CD player that plays audio CDs and I noticed a little "Mp3/wma" logo on it too so I wanted you all to know that ISO9660 + JULIET totally works for cars with radios with CD players of similar type.
Which is great!!!
Here is an image that explains all you need to know. I used a CDR, 80 min 700MB media and it worked just grand.
1. Mode -- Select BUILD.
2. Drag and drop MP3 (or .wma) files OR folders into the left box.
3. Select Options Mode1, and 9660 + JOLIET trust me this is the one that works.
4. Click the big disk button to burn it.
Success!! --I was able to fit over 100 songs (some 320k encoded) to the disk.
