Awesome work 14124all! Thanks for posting.
When I first got my Fuze, I ordered a cheap View A/V cable from eBay on the off chance the line-out might work. Of course it didn’t, and I’ve been thinking about modding it ever since. I think all that’s needed is the jumper you describe, but I’ve been afraid to try it. I’ll give it a shot and post my results.
Could you post a pic of your cable? I’d like to see how you squeezed the extra cable into the 30-pin connector.
Also, what kind of wire did you use for the jumper?
