THE PANASONIC VX505MS. To tell you the truth, other than the fact it's a good sounding head unit, you didn't click on this because it sounded good, you've clicked on this because this is one of those flex pieces. That mechanical arm comes on command, and acts as a tweeter for whatever you're listening to, why? God knows why, but really why not? Get it and flex on your friends, ask them if your futuristic head unit has a retractable arm, or just press it when they get in. Bluetooth is included, and tested. Amplifier has been tested successfully. CD is not working. MD untested as we don't own the correct sized MD, also seems to be hesitation on the retraction when you're putting an MD in it. note : you won't have any issues just using this as a bluetooth device. Harness Included. --> On the specs, it's a double DIN unit. Other than that, I can't tell you much, as I could not find any spec sheet / manual describing the product online. We know it has a decent powered internal amp, it sounds great, and its one of Panasonics top dogs, so much so we found one for sale in the box for about ~5000 AUD.
