Things I want to buy to go with my phone

I plan to use my mobile, a Nokia E50, as the hub of my digital life (TM). I want it to be satnav, an mp3 player, the works. I need the following things:

Bluetooth headphones

For listening to music while on the move. There are millions of these available; a list will eventually turn up here.

Satellite navigation

For navigating around in the car. This needs a few things:

Software

• Route 66: http://www.66.com/route66/products.php?cid=UK&sec=8&ssec=0&prodid=1698
• Wayfinder: http://www.wayfinder.com/products/wayfinder_navigator.en.php?content=compatible_phones
• Possibly others: http://www.pocketgpsworld.com/

All software has the option of being bought with or without a GPS receiver, so I can look at buying it separately if it's cheaper. Software doesn't seem to come on micro-SD cards, so may need one of them, below.

Hardware

• GPS receiver, see above
• In car charger for phone

Music in the car

Some sort of Bluetooth thing that connects to my radio. This could be a Bluetooth widget that lets you plug your own headphones in (see Bluetooth headphones above) + a FM rebroadcaster (which I already have), or some dedicated item like the Nokia Multimedia Car Kit CK-20W or Nokia Advanced Car Kit CK-7W.

Typing while on the go

Requires a Bluetooth foldable pocket keyboard. Maybe steal Jono's, or buy one.

Random extra stuff

Might need a larger micro-SD card to put all this stuff on, especially if I start watching video on the phone.

Need a way to encode video so that it's watchable on the phone and as small as possible. Investigate ffmpeg, mplayer, gstreamer, etc.

Battery life will take a beating with all this stuff. Buy an additional battery to put in the laptop bag? How much are they? How long do they stay charged?
