Is RNS-315 to RNS-510 upgrade worth it ?

[LazLon]

Hi,

I am looking to buy a new Tiguan Match which comes with RNS-315. Upgrade to RNS-510 costs about £1200. Is it worth it ?. My main reason for the upgrade is to get a bigger screen.
Also, do these units take full UK postcodes ?.

Thanks,
Laz

I've seen this question asked to dealers quite a few times. General response seems to be that if you're using sat-nav regularly then it's worth considering the 510, due to the larger screen. Also they point out that the RNS-510 won't make the car any more valuable when you come to sell it.

Both 315 and 510 have postcode search.
