Hi all, Fitted a new vms 3000 gps system to my 06 hilux yesterday, after install i couldn't power up unit whilest vehical was off. Even tho my spare battery voltage was 12.9v... once i started my vehical the unit powers up no worries. But when i have turned off the motor and the voltage drops to about 13.5v the unit shuts down.. Has anyone else had this issue before, i wouldn't have thought it needed 14v to run the unit, if thats the case i can't even listen to the radio with the engine off.... I have a dual bat system fitted, and i have the main power supply for the unit comming off my spare battery, would this make any difference??? Any thoughts would be helpful
Thanks

My VMS unit has been in for over 6 months with no hint of a problems such as yours.
Have you measured the voltage at the unit with the engine off? Maybe you have a poor connection somewhere and are dropping a couple of volts.

Most car units have a wire for power and a wire for power to the memory.
This normally goes to an always on source and then you wire the units on /off
switch to a switchable accessory source.
Perhaps you havent got them correctly hooked up.
Just a thought

Reason I ask is that VMS is a USB connection and runs off 5 volt, can't wire direct to a 12 volt system...
Not sure if that was the question...
cheers
