You should check OpenStreetMap.org's quality in your area. (iPhones use it, last I heard.) Los Angeles should be pretty good.
The other option, Google Maps over a cell data connection, might be workable but that's competing with just getting an Android tablet and mounting it on the dash with cables to connect it to your existing audio head unit.
HD Radio in an RPi-accessible format is an interesting one I hadn't thought of before. A quick google gives me a few decent hits:
1. Silicon Labs Si477x series, 476x series, 468x series. Example: http://www.digikey.com/product-detail/en/SI4777-A20-GM/336-2266-ND/3164513 http://www.digikey.com/product-detail/en/SI4777-A20-GM/336-2...

- Moto7451 12y agoI've found these chips but a lot (all?) of them require a large purchase order and an NDA. I presume because of the encoding or something silly. I believe the HD Radio tech is obnoxiously patent encumbered. Meanwhile AM/FM chips are dirt cheap. C'est la vie.
