Suggest me a good OBDII reader?
The check engine light on my gf's Chevy Cruze just came on and I want to be able to read the codes by myself instead of running around to a garage to get them. Any suggestions for a good OBDII reader? I've seen the newer ones that work with your cellphone via bluetooth...do you guys use them? I'm open to suggestions but would prefer newer tech that works with your phone and it has to be able to read Mercedes check engine lights as well (in case mine pops up one day).
