Ok here's a solution for you.
I had same problem.
There's a receiver under the dash behind the dic.
Pull it out replace it with a different one (junk yard pick n pull cost 7$)
Or buy from someone here for 30 with key.
And it's gonna work perfectly.
After that there's a thread I made about how to get a really good range.
Look at my post you will find it.
It's easier than you think. Good luck.
