Just seen a really cool looking bit of kit.

You get the OBD II key that send data wirelessly to your iphone usings apps such as rev and dashcommand.

You can then see all the info on your car.

Has anyone tried these things? How are they?

Ive used the bluetooth OBDkey on PC's, windows mobile and android. They work great and grab engine ecu fault codes with ease.

Shame apple wont allow the bluetooth to be used :-(

Thanks. Just picked up a elm327 bluetooth device for £17.

With a jailbreaked iphone and roqy its supposed to work. Apparently jailbreaking isnt illegal so i can mention it here. Only illegal when you download dodgy apps.

Will see how it goes when it arrives.
