I'd recommend a TomTom with a Traffic (RDS) receiver. From the One T to the 930T depending on budget.
The latest range of TT include LIVE products. The TT LIVE include a Vodaphone SIM so traffic information can be downloaded for a monthly subscription (£10/month I think). This is quite an expensive option and I'd say this is for professional drivers only ie. salesmen and delivery drivers. Alternatively a RDS Traffic receiver aerial can be bought for a one off price of £40. Importantly though this aerial is bundled free with the older ranges of TT!
The higher range of TT, 530T and above come with the latest features of advanved lane guidance and IQ routes, both worth while features.
