Good ol’ Mapquest has an iPhone application capable of providing driving directions. Called Mapquest 4 Mobile this app doesn’t look like it can provide dynamic directions – such as “turn right on Main Street”. But it is pretty much like taking directions printout with you in the car – just like you did in late 90s. Kinda retro – but it’s free.

Now they have GPS navigation systems with OLED screens in Japan. Called DTN-VX003, and manufactured by Trywin this device has a 4.1″ touch display with 480×272 resolution and offers a spacious 4GB internal memory.

It’s only been a few weeks since the new iPhone 3.0 operating system has been released and we already have a handful of GPS navigation system applications available/ or soon to be released. Let’s recap what we have so far:

Hemisphere GPS XF101 is an add on to the field computer “The Archer” built by Juniper Systems of Utah. It is a GPS receiver that integrates with the Archer handheld to provide sub-meter DGPS for location-based applications. It is lower power device so you can still use your handheld PC for a long time and is rugged enough to be even working in a pool.

It looks like Nextar is trying to stay afloat in this economy by releasing GPS navigation systems fit for every budget. Their latest is the Nextar 43LT which has a 4.3″ screen and offers life traffic updates from Navteq’s RDS-TMC service (see coverage). It only costs $170.

Garmin Dakota 20 is Dakota 10’s bigger brother. Announced at the same time Dakota 20 has pretty much the same appearance as Dakota 10 but when it comes to specs it hides a lot inside.

Garmin Dakota 10 is one of the latest outdoor GPS handheld devices from the company. Compared to the Garmin Oregon series, the Dakota 10 is a lot cheaper and lower end.
