Please read the solution that resolved this problem for may others. Most likely, you have already tried this. However, the antenna of your Nuvi 300 is the same as the entire 3xx & 6xx Nuvi series. I know this because I have worked on them.

If the above procedure does not work for you, the entire antenna assembly will need to be replaced.
The other option is to purchase an external antenna for your Nuvi and plug it into the external antenna port (gold connector) on the Nuvi antenna assembly.
