As far as Asus is concerned, Neil Sedaka was full of crap when he said Breaking Up Is Hard to Do and has made the decision to end its short-lived Garmin-Asus business arrangement. When the contract with Garmin expires in January 2011, Asus will split the partnership and resume selling its own branded handsets.

Like any good break-up, the two will attempt to remain friends and collaborate on navigation software development, but that will be the extent of their dealings. With the partnership dissolved, Garmin will be free to distribute its navigation solutions to other handset makers, which could include Sony and LG, two companies Garmin previously worked with.

As for Asus, the company can get away from churning out LBS (location based service) and GPS specialty handsets.

According to Bensen Lin, vice president and general manager of Garmin-Asus, his company will launch its Android-based Nuvifone A10 smartphone in Taiwan on September 10. Those who want to get a jump on other buyers can put in their pre-order now.

Android's Froyo build (Android 2.2) isn't in the cards for the Nuvifone A10, at least not initially, and will instead ship with Android 2.1. It will also come with a 3.2-inch HVGA touchscreen display, 512MB of RAM, a 5MP camera, Qualcomm 7227 processor clocked at 600MHz, Bluetooth/Wi-Fi, and other odds and ends. As with previous Garmin-Asus phones, the A10 will come heavily promoted for its built-in GPS functionality.

No word yet on when this one will ship stateside.

Rolling out of T-Mobile this week is the Garminfone, which as you might have guessed is both a smartphone and GPS. Asus had a hand in building the device, opting to stuff a Qualcomm MSM7227 processor (600MHz) into the 4.57 inch x 0.5 inch by 2.46 inch smarthpone rather than the far sexier Snapdragon chip clocked at 1GHz.

Other design decisions include a 3.5-inch display with a 320 x 480 resolution, 4GB of internal memory, and a 3 megapixel camera. Living up to its namesake, the Garminfone comes with extensive navigation features with turn-by-turn directions, voice, weather, traffic, and gas prices, and you can even record your own custom voices as navigation prompts with Garmin Voice Studio.

Unlike other smartphones, where GPS is typically tacked on as an afterthought, the opposite holds true for the Garminfone - it's primarily a GPS with smartphone capabilities. Layered on top of Android is a custom home screen, though it does come preoloaded with Google Mobile Services giving you instant access to Google Calendar, Gmail, YouTube, and GoogleTalk.

The Garminfone is available now for $200 after $50 mail-in-rebate card and with a 2-year service agreement.
