12 Volt Source for a V1 ?
I may have to use the rear seat cigarette lighter in the center console as a source for 12 volts for my Valentine V1 radar detector and aux. display using the Direct Wire Power Adapter. Has anyone found a better source? Perhaps under the dash or in the overhead console. I don't have my CLS53 yet (delivered next week), but I don't recall seeing a cigarette lighter in the front. After it drained the battery in my previous CLS63 S, I am not planning to use Valentine's SAVVY unit.

Reply from Valentine Research
For anyone interested in installing a V1, I'm posting the reply that I received from Valentine Research about their SAVVY unit.
If you purchased your SAVVY before October 16, 2015 (serial number ending in 0018 or lower) you should send your unit back for a firmware upgrade. Valentine support says:
"Because the power supply to the OBD2 port is on all the time, the Savvy turns itself on/off based on the voltage level. Since the nominal voltage for a lead acid battery is 12.8 volts, the Savvy is designed to power down, once the voltage drops below 13 volts. In a vehicle equipped with a Lithium ion battery, the Savvy may not shutoff properly since the nominal voltage is 13.2 volts. When the voltage remains above 13 volts, the Savvy assumes the engine is running and thus will keep communicating with the ECU, which could lead to battery drain.
First, I would suggest sending the Savvy back for the firmware update. Once you get it back, install it and test it to see if it’s functioning properly. If the V1/Savvy doesn’t shutoff with the ignition, I would stop using it."
I will report back when I have done this and if I find that installing the alternative Direct-Wire Power Adapter via a 12v source is not convenient.
