Newbie few questions

[jacko gt tdi]

New to me 09 gt tdi just a few niggles if any one can help.

Leaving/coming home lights don't seem to work have turned on as described maybe this has been deactivated? I liked this feature on my mk5 golf.

Interior lights come on when car is unlocked/locked but stay on whilst driving?

Rns 510 ,think this is older model no bluetooth etc,all works fine apart from satnav is stuck on random place and no satellite are found, can this be sorted or is it to old and not worth doing?

Thanks

Think sat nav is sorted , got an aerial off the bay £5,interior light fault looks like the contacts are badly worn not sure it can be sorted ,the leaving/coming home lights still not sure will not whats up might be worth a look on vagcom when i find some one near me.
