The iPhone 4 fits in the tray and the Sony deck we sell is marine grade
The medallion system is awesome. No moving parts, can withstand 1000 psi of water to the face and still function properly and is plug and play with factory harness. Capable of connecting to an I pod or just put your flash drive in ad go. Don't have worry about ruining a few hundred dollar I pod if the deck fails to protect it. Just my. 02
I want to see it get hit with 1000psi of water and still work to believe it.
These head umits have been used for over 10 years in marine applications by high end boat manufacturers like malibu, mastercraft, and cobalt
