I am just investigating these plug in boxes that you can then connect your smart phone/tablet up to to get real time diagnostics. I have read that iphones won't work with a bluetooth one and that I would need a WLAN one, is this correct? In any case I have seen this "WiFi WLAN OBD2 ELM327" on ebay for 99p. Has anyone with an apple device used anything like this?
! I didn't want to spend £35 quid on dash command to find it wouldn't work, it's a pricey app. I have read you can jailbreak and then use bluetooth but I don't really want to have to do that just for one app.
