advice

i have bought a free view box for in my lorry but need to fun it through my lap top what wires do i need to acheive this ?

It will be quite a fiddle and hassle that - a much better solution that is designed to work on your laptop:

Play.com (UK) : August PC / Laptop USB Freeview / HDTV Receiver (Black) : Computing - Free Delivery

With the added bonus that it will use the USB power as apposed to a 230v inverter

are they any good i have one of these in the draw but never used it and the one i bought at xmas seems to be one that would have more signal strength

I’d certainly give it a go, especially if you already have one.
