How To Maintain Electronic Settings While Battery Is Disconnected

Post by Oka »

Hello folks,

What would you recommend to use, to maintain the Volvo's radio settings, while replacing a battery. Also, for how long can such device be used in the process?

Cheers.

The only thing I lose is the clock, no big deal bc it takes < 1min to reset the clock.

If you search forum, then some ppl use the 9V battery.
