Rns 315 or 510 or aftermarket

[jasst]

My new to me sel estate only has rcd 300 and I would like built in sat nav as old car had rns 510 +Kufatec basic, so do I go for either a RNS315, OR 510, or how about one of the aftermarket ones? are these any good? quite like the sound of this https://www.ebay.co.uk/itm/7-Built-in-D ... 0022.m2048, but are they any good, or does anyone have any alternatives that they recommend, must haves are good sat nav, integration with steering wheel controls, Bluetooth, and integration with ops. Thanks.

I have just had the same dilemma. I have a Kenwood DNX7170DABS out of my other car. But with the fact mic, DAB aerial etc were already there I went with this

Brand new as stated and as a bonus I drove up to collect and the guys at the shop fitted and coded everything while I waited F.O.C

Really happy with it.
