This is an 8-inch portable navigation system, the SAYKO model from Gomela. - Brand: Gomela - Model: SAYKO - Power: DC 9V - Size: 8 inches I am selling this because I purchased a new navigation system. The navigation function is outdated, and the types of GPS it can pick up have decreased, so it's honestly not usable for navigation. I personally use my smartphone for navigation, so I used this as a one-seg TV, DVD player, and mirror monitor. The original base is missing, but I modified a 1-DIN space to create a storage compartment, allowing for a seamless installation. You can also still purchase a base online. The GPS antenna is built-in, so you don't need to use the GPS antenna in the picture, but I'll include it as a bonus. I am open to price negotiations, so please feel free to make an offer.
