Best accessories for TM506?

[andrewpdx]

I know there are a few recs buried in the main TM506 thread - but what are people's favorite accessories for their TM506? For example - stereo headphones? How about an FM broadcast to use the MP3 player in the car? (A common thing with iPods I guess but I've never owned one.) It'd be nice if there was an accessory with both a headphone jack and a duplicate of the power jack, so I could use the phone in the car off the car battery but also get audio out of it.

I got an 8GB M2 memory stick from Amazon and also the data cable there...

Anything else?

I use my mp3 player in the car by buying a Sony Ericsson 3.5 adapter and plugging the cable into my Ipod port in my car. Works like a charm. You can find the OEM 3.5 adapter on Amazon for 1 penny. yes, 1 penny...but they charge you like $5 to ship it.
