I have read a lot but I am still doubting between the two versions Appradio.

I will do the installation in a new Nissan Micra with an iPhone 4 already jailbreaked.

I want to use the Appradio to listen my music and podcast. I need a good handsfree set and occasionally will need GPS capability.

I don't want to loose the steering wheel remote functionality and plan to install a backup camera.

Which backup camera will fit with the Appradio? Do I need to buy the Pioneer retail accesory?

For the wheel steering interface, do I need a special cable set?  I see this one

Would it be ok for Appradio and my car?

I saw that the first Appradio vers. has a steering wheel setting menu, the Appradio 2 not. How this function is programmed or set, on the Appradio 2?

I guess the SPH-DA01 will fit to my need, but the Appradio 2 has maybe more functions I don't even know.

Your help would be much appreciated.

Get the 2 the first one was complete garbage. The 2 is good but quirky sometimes but if your patient I think it will be great. Steering wheel adapter I used the axxess swc and it works well except I can't control my presets on the radio not a big deal to me though

Thank you Woody7795, for your reply.

I didn't know the first one got functional issue.

Is Access SWC compatible for both version (1 & 2). I saw it is quite popular in the US, but difficult to get in Europe. I will try to found a reseller in EU. I left a link in my first post of a cable set compatible for steering wheel interface. I was wondering if this cable is for the same function. According the Website it is, but it seems to be only a cable harness rather than a full interface.

Again thank you for your feedback

Edit: I found a full interface with cable harness for Nissan Micra and Pioneer

How the Appradio one works with the last firmware? Does the update bring improvement to the usability/functionality?

I'm using Sygic on my iPhone. Is it possible to use Sygic from the Appradio screen? If not, is it possible to mirror Sygic with Appradio extensions?

Thank you for your answers.
