It's been a while since we heard anything from Sanyo on the Gorilla tip, but according to the company the venerable PND will see three new models hit the scene on April 24. These bad boys will feature two gyro (velocity) sensors and an acceleration sensor, allowing the device to keep an accurate account of your location -- even when GPS reception poor. If that isn't enough for you, the new Gorillas sport an 8GB SSD (twice that of their predecessors) and an optional rear view camera for your vehicle. Prices have yet to be set in stone, but it's believed that the NV-SD730DT, featuring a 7-inch LCD display will fetch ¥90,000 ($899), while the NV-SB540DT (5.2-inch display, plus tuner for real-time traffic updates) and NV-SB530DT (the 5.2-inch model, sans tuner) will run for ¥70,000 ($700) and ¥65,000 ($650) respectively. No word yet on a Stateside release.
