Radio turns on in telephone mode HU-1205
 

Hello, I have a VOLVO V40,2001, with its default radio VOLVO HU1205, but whenever i turn the radio on it turns in telephone mode(just shows TELEPHONE) not in FM/AM/CD, and every time i have to volume up so it goes into FM mode.

Any solution?
Thanks in advance!

I think you will struggle to get an answer to your question. The HU1205 was a very rare option when new and now the technology is more or less obsolete, so not many owners will have any experience. Hope you get it sorted.
