I would like to upgrade my stereo to a more modern unit with Bluetooth, GPS, back-up camera, DVD, MP3, etc. but do not want to cut my dash. I found what appears to be a plug & play unit that fits the bill in the link below. Is anyone familiar with this piece? I'm sure it's a Chinese sourced product and that's fine but I hate to be the guinea pig on a completely unknown item. If not, does anyone know of a product like I'm describing? If so, a link or description would be greatly appreciated.
