I have an OEM Fujitisu head unit that I removed from my BRZ because I wanted a larger screen. It was in my car for about 1 month and is in excellent condition. It comes with the GPS antenna and the map sd card for North America. Part number 86271CA620. This part lists for $1685.22 on subarupartswebsite.com. I will sell it for $1100 with free next day delivery.
I'm in Florida not west coast but I will sell mine for $650 shipped I never use the navi and want to upgrade. I only have 1300 miles on the car so the radio is in excellent shape can provide pics if needed.
get an aftermarket, the stock one SUCKS!!! I just put my Garmin on the dash above it. I'm going aftermarket soon too because even the Bluetooth audio sucks, it never connects or takes 5 minutes to reconnect after you shut off the car and restart. it's a joke.
