Radio Reception after Car Detailing

[LouUKUS]

Hello everyone,

I am a newbie wondered if I might be so bold as to ask a question?

I had my 2007 Yaris detailed last week after some bodywork was done. When I picked it up the saved radio stations were lost (which is fine) but the reception is now scratchy on stations that were previously clear.

Any suggestions as to what I should be checking?

Many thanks in advance folks - it's appreciated.

Lou
