so i just installed my avh-4200dvd today and i have a wd live tv hd media player that i want to install in the truck... i have no idea how to power it i dont kno if i should get a power inverter with a noise filter or a dc voltage regulator. the unit uses a 12v ac to dc wall transformer so a 12v dc voltage regulator should work right... also i have kno idea where to find one lol been googling for weeks... my other thought is if i do a power inverter im affraid i will get lines in the video playback. about 4-5 years ago i had an inverter for my xbox 1 in my integra and had alot of problems with engine noise showing up on the moniters...
