Anyone with Symbian Belle onboard might like to check out two software items, both free. 'Nokia Car Mode' essentially takes a common subset of applications needed while driving and presents them in large fonted, finger-friendly form, to avoid distractions and make it easier to concentrate on the actual motoring. 'Nokia Play To' uses one-way DLNA to let you show photos and videos (and listen to music) on your mobile wirelessly on your TV/home hi-fi. Links below.

Nokia Car Mode is built on Qt and is free. It "reduces driver distraction by making available the most relevant applications for in-car usage, such as making calls, using navigation and listening to music." Comments welcome if you have a Nokia 701 or 603 and have tried it.

Nokia Play To "lets you show photos and videos taken with your mobile to your friends wirelessly on your TV. Or you can listen to your favourite music stored on your mobile with your home audio system. Just launch Play To, select the device and media you want to play. No configuration is needed once WLAN is on and all devices are connected to the same network".

This new version, 10.2.10, is for 'NOKIA BELLE ONLY' (Nokia's CAPS) adds proper localization, improved connectivity handling from the status bar and an on/off homescreen widget.
