I'm thinking of going for a 7839.
A few initial questions:
There's no mention of ipod control. I have a rather old 'classic' which has the old, large connector. Could this be connected to one of the usb ports and be controlled from the headunit?
Does the headunit have wifi capabilities or would I need to get the 3g/4g(maybe wifi) dongle? I wouldn't often need internet acces, I was thinking of letting it connect to my phone and use it's 4g connection when needed (updates etc).
My car currently has the mfd and a cd drive(no nav), which means it has the single slot frame 'carrier'.
Will this need to be removed and a full nav unit carrier be installed or does it not use any of the original carriers?
Is it just a plug and play unit? I don't have the logic amp, but I do have an amp in the boot for subs, currently switched on by the diversity antenna 'live' (a white wire in the loom iirc, it works!). Would I need to re wire both of these or are they (ie diversity) fed through the 'big' radio connector (flat pin in my case), that's behind the dash in my case (ie not in the boot since I didn't have nav).
Thanks for any replies and help. I realise some of these should be aimed at the seller but it's nice to be fore-armed
I'm glad you brought the ipod control up as I forgot to mention it. At the moment, when I plug my iPhone in it does charge, but I don't have any way to control the phone's music from the head unit. With that said, I've literally spent about 2 minutes playing with that function, so I'm nowhere close to admitting defeat.
I'll eventually do the CarPlay dongle, which will give all the functionality of Apple CarPlay on the Android unit, to include ipod/music/spotify control. I'm guessing there's an Android app available to interface to the older Ipod, but I don't have a specific recommendation
The head unit does Wifi (and does it well), and I believe that's the only way to connect. Even the 3g/4g dongle Xtrons sells simply broadcasts a wifi signal and uses USB for power only. I'm currently using an AT&T wifi hotspot in my glove box, but I would think you could do without cell connectivity fairly easy. Download an offline maps app (there are several available), download your music to the unit, and allow it to connect to your home wifi when it's parked at home.
The full carrier would need to be removed, regardless of which carrier you've started with (nav vs non-nav). The unit includes it's own brackets, which are terrible. I just saw a post this morning on the German FB group that someone is looking at creating 3D-printed brackets which supposedly fit better. We shall see...
For you, I believe it should be a fairly simply install. You won't need any of the extensions listed above, possibly an antenna adapter, and you will need to use the included GPS antenna. As far as the amp question, I'm honestly not sure.
