WTB: RNS 315 or 510

I am looking for a good condition RNS 315 or 510 (315 preferred. Willing to pay a fair price depending on the HW and firmware revision, condition, and options. Let me know what you have! I am in Suwanee, GA and this will be installed in a 2012 GTI that currently has the stock basic radio (no touch screen).

Edit: Also looking for a good price on an RCD 510.

I'm new to GTIs, so if I need additional components I'd consider buying those as well (ie, GPS antenna).

Thank you!

Bump, found a few leads but haven't pulled the trigger yet.

I would also consider a good price on the non-Nav units (RCD 510 for example).

Thank you

Found one, no longer looking. Thanks!
