2009 Pontiac Solstice GXP Coupe 001136
At the GM Nats in Carlisle, Dabbler had a rear license plate frame that had a Bluetooth b/u camera powered by a small solar charged battery, paired with a smartphone or monitor in a holder. No wiring, no radio swaps, no mirror swaps, and available for $70-$200.Oh man, I've been trying to avoid installing one, not keen on having to route the wiring.
Also, in case I do eventually install a rear cam, I'd probably hook it up to a rearview mirror screen in order to keep the factory looking headunit.
I haven't used one, though. He found his at Costco, IIRC.
