Firstly, apologies if this thread seems similar to other threads I've recently created. I did think about continuing one of those, but as I'm asking for recommendations about headunits I wanted to canvass more than just those that might be following those earlier threads.
I've managed to demo a few units in Palmerston North at Repco and Supercheap Auto, but the range isn't very big, so most of my research has been online. But I've found that details of many headunits is a bit thin, and Youtube videos, which are usually reliable for giving detailed reviews/demos of devices, are surprisingly hard to find. So I'm hoping that Geekzoners might be able to provide some first hand insight into the models I'm looking at.
I'm starting to lean towards the JVC range. I tried the JVC KW-V320BT at Repco and it was pretty good. My online research shows newer/fancier units (such as the V30BT or V51BT), but I haven't been able to try one out. They look similar to the V320BT, but have a few differences. The V51BT has an articulating screen, larger screen, while the V30BT has a slightly smaller screen (non-mech) but has a rotary volume knob (which I quite like). They also tick all the boxes I started with - Bluetooth, USB/iPhone support, input for a reversing camera. They don't have Carplay, which I don't think is worth the extra money, but they do have AppLink mode. This also seems a bit glitchy, so I'm not planning to make use of it.
Has anyone got any first-hand experience with any of these units? Would you recommend one of them?
