I have an e34 touring with a c43 radio. The radio works great, except for the following problem, which is starting to wear on me and my passengers....

When the radio loses its fm signal, there are a couple of dead spots on my daily commute and around town, the radio jumps from its preset station and starts to randomly scan the fm channels. The scanning continues until I hit the memory button or a preset channel, and also reestablish an fm signal. At its worst, this goes on for a couple of minutes.

I could understand if I just had static when I lose the fm signal, but I am perplexed by the random scanning. Any thoughts/guidance would be much appreciated. Thanks.
