Are cheap cable remotes for the iPhone and iPad good for listening to podcasts I like to listen to podcasts while driving - but I can't use the iPhone's touch interface to play/pause podcasts because it requires looking at the iPhone long enough to cause an accident.

I'm looking for a physical pause/play button I can operate by touch and I've found this product on eBay Cable Remote Music Control for Apple iPod Nano 6 Touch 3 Classic iPhone 4S 4 3GS

I've had issues before with a car's built-in iPod control that would mark a podcast as completely played even if I listened only to a short part of it and that made that car's iPod control completely useless for me.

Does anyone here has experience with that iPhone remote and knows if it works well for podcasts?

Recommendation for alternative products are also welcome, as long as the alternative is cheap

if it makes any difference the iPhone is connected to the car's radio speakers with a cable connected to the phone's earphones jack.
I have the same issue, and here's the workaround I use:

I create a playlist and add the podcasts I want to listen to that day. 

It's a little time consuming but then I do not have to try and find the podcast on my ipod while driving.
