Hey,
I appreciate the response.

It is indeed the older style FSR, with the thicker prongs. And it was quite hot when i did a test with it. I didnt see any prominent size differences. Just wanted to make sure this could be the problem because i recently had problems with my radio not working. I went under the spare tire and unplugged the battery, doing a full reset. Now im a new BMW owner so im not sure if it would have an affect? I just wanna make sure i get my moneys worth for this. If you are sure i need to replace it would it be possible to redirect me to a good site to purchase one on? (Im not a huge fan of ebay)
Thanks alot,
Greg
