Hey everyone, problem resolved.
It seems that the digital clock reset becomes an early warning sign that the battery will eventually die (this one lasted over 5 years).
Thanks everyone B)
On my RX when switching from radio to CD´s the antenna retracts automatically.
On the other hand on the GS300 it remains extended as long as the sound system is switched on.
Does anyone know how to disable-program it?
Thanks in advance from sunny Madrid.
