Sorry to bring this up again but I'm well confused!

Just fitted a new JVC 722 HU to my Octavia (2004 Elegance Estate PD130). Everything's OK except for the radio reception, which is where I'm confused.

I'm confused as to where the antenna amplifier is. Is it in the original radio (in which case I need to buy a booster), or is it in the antenna itself (just need to buy a powered antenna lead). :confused:

Also, assuming I just need to power the antenna, where is the best place to take the 12V feed from? :ne_nau:

As a side note, I'm pretty impressed with the unit itself - can play stuff from a pen-drive via the USB port on the front. really handy!

Also, there was no need for any additional wiring changes (other than the antenna). The JVC connectors have no connection to the K-wire, and there are bullet connectors for switching the yellow/red wires

Thanks

Paul

The amplifier is in the base of the antenna. The original HU was able to power this through the cable. An aftermarked unit requires a separate amplifier simillar to the one in this picture.

You also really need to disconnect the "K" wire, as on the standard ISO connection this pin is used for something else, and if left connected earlier VAG diagnostic tools will be blown up if plugged in to your cars diagnostic port. The power is also reversed so if you find your HU forgetting its settings thats why. The linked item above will sort all the issues above and can be installed in minutes.

there is a booster that fits in between the aerial and the radio and you connect the 12v feed to it from the blue wire on the back of your jvc unit so its only powered up when the radio is,the part is an autoleads PC5-52,hope this helps

Thanks! That's what I wanted to hear - music to my ears (literally)

Mine works without this booster ... which is £13.50 at Halfrauds.

Halford claims this part to be an antenna adaptor and signal separator. From their description it seems it is good for supplying an already amlified antenna with power. But it does not amplify the signal.

Is the Halfords description wrong?

Its the correct part trust me ,halfords description is poor thats all and as said above its not an essential part as you will get some FM reception without but with one you will get a clearer signal and more stations especially on MW:D

Some more news on this topic. Just got back from Halford where I picked up a P5-52. I tried my new JVC radio with and without it right in the parking lot. Reception is definitely much better with the part fitted. I did double-check the part

Interesting, Michael
