Google Maps Navigation for UK and Ireland

So now turn-by-turn navigation is now supported on Android outside the US for UK and Ireland - and yes it works in the Republic. So I was interested to try it out. For some reason I couldn't get it on the Marketplace - could be an Acer Liquid build thing. So I found package on Android Freeware and manually installed it.

I wanted to try it out immediately, but I cycle to work, rather than drive, so I came up with a plan. I'd connect a set of headphones to the phone and I could at least check out the voice navigation while I cycled, you know "turn left in 200 meters" that sort of thing.

Now there was just one problem: I like to listen to music when I cycle. I know, not terribly sensible, but a lot of fun. Could I do both? Thanks to Android's multi-tasking I was able listen to some sounds with the occational navigation voice-over giving me directions. Sick!
