Radio and Nav system will not turn on

[Falcon75]

I have a puzzler: I returned recently from a 2-week vacation and started my 2006 V8 Vantage. It's always kept on a CTEK battery tender and the charger indicators were fine before I unplugged it. The car started normally, but the radio will not power up and neither will the navigation system. No other electrically powered system on the central console seems affected. I checked the passenger side fuses and they appear okay. Any ideas what my problem is?

i would suggest getting a foxwell 520 OBDII reader (or equivalent) with the aston martin software package. it will give you info on a lot of the options and any faults associated with them.

of course, it might simply tell you "they aren't working"...which would be disappointing.

Could be the battery. I’ve had the same problem. Car appears fully charged & starts but ICE doesn’t fire up. It’s very sensitive to the battery output.

Happily, a new battery solved my problems. Whew! Thanks.
