Just been reading the latest Evo, and given that so many people seem to be currently talking about hooking up their ipod to their standard radio, I thought I'd mention the advert I saw for a company who's website is
www.iplug-rds.com - they make a device that claims to display track info on your radio.
According to the advert and site, the device uses the RDS system of the radio which normally shows you station names to display track names, info etc.
No idea how good it is and the website seems very basic and based in Hong Kong. I'm not claiming to of used the product, just thought some ears/eyes may be interested. Priced at $190 the exchange is currently set to make that a very reasonable price.
