The Dynavin unit is great. Plug n Play with the factory stereo. The interface is good, the Maps installed on mine are the IGo ver 8 and they are readly updateable, with versions for Australia & New Zealand. I've had no problem being able to read the screen in the NZ sun. The Media play is good I have a few movies on a 32GB stick drive which is great for those time when waiting for a shopper to finish. I've install a reversing camera on it, which work great. Overall the fit and build quality is impressive it really does look like the OEM product but for a fraction of the price. I'd recommend it.
