Revainrating 5 out of 5

So far so good, I installed it according to the instructions.

So far everything is fine, I installed it according to the instructions and it seems to be working fine. It should be noted that not all of the computer's RAM is returned at once. I installed it, took it for a quick trip to the store and found that my remote control locks didn't work and my driver's side side window didn't work. I drove further km according to the instructions (15-20 km) and everything worked fine.

Pros
  • A sea of positive emotions
Cons
  • Not bad
