Alright, just so I"m totally clear on this. I can get pretty much any bluetooth adapter to plug into my OBDII port and then just use whatever software? Sorry I'm a little slow when it comes to some of this stuff!
I will buy an adapter and then get the torque app for now since I've read nothing but good about that. Then look into some more vehicle specific software if needed.
Seems like for the price these are the way to go unless you get into the big dollar scanners.
No, you cannot buy any bluetooth adapter - you have to get one that will work with the software and the phone that you own - if it is android is will most likely be torque. So, look for the reviews on amazon or on the Torque site to make sure that whatever you are buying works with the software.
So, what I got that works well with torque is this bluetooth ODB II

I KNOW that one will work with android and torque I used it this week, I ordered it 2 weeks ago and it has been flawless. On my car I have vendor codes that it does not know (Smart Car), but links to a web site that explains the codes for you. I used it to reset a fault and have been playing with the real time stuff for fun, it could be scary to play with when you are driving, i do not suggest that
You can also save all the files and codes, upload them to web servers, email them to yourself, change the look and feel, background, it works very well.
IF you have an iPhone this bluetooth OBD II adapter will not work and the software will be something else, I looked quickly and could not find if you had that OS or not.
So - Android - Torque with the OBDII link in this reply
iPhone/iOS - I do not know what software is the best, look on iTunes and make sure the OBDII works with that software.
Hope that helps....
