Had a piranha dual battery setup (DBE180S) installed proefssionally into my petrol 2006 prado GXL two weeks ago. went away for the weekend, 2 hours north, with the waeco cf50 loaded up. fridge worked a treat, stayed at set temperature the whole time.
problem is that my autotunez dvd/gps unit stopped working properly, sound but no display. the unit needs a stable 12volt power supply, and previously have had to charge the single battery to bring up to full charge before the screen display came on.
crank battery is nearly 2 years old, and the car usually doesn't get driven much during the week or the weekends, except for the trip north one or twice a month.
i've seen some posts on problems with charge of the auxilary battery, but not about the crank battery.
any thoughts on what could be happening here, or suggestions on a fix for this
