Some users may have noticed that the icons on screen (such as the Zoom + and Zoom - buttons) can flash when the GPS lock button is used.
The high resolution screen and display chipset within the Adventurer 7000 means that if the GPS position is locked on within Memory-Map the button icons will flash as the screen is re-drawn as your position changes. The actual amount of flashing will depend on your speed and map scale selected. It is worse at higher speeds with smaller scale maps as by definition your position and the screen therefore need to be re-drawn more frequently.
It is also affected by the GPS Position Circle (extra rings around our current position) and the Velocity Vector (the variable length arrow from your GPS position). We therefore recommend turning GPS Position Circles off – to do this tap and hold on your GPS position and select Properties from the menu. Tap in the Range circle box and then tap the Kbd button and use the keyboard to set the value to 0 and then press the OK button. We also recommend a Velocity Vector time of 1 min – to do this tap and hold on your GPS position and select Properties from the menu. Tap in the Scale box and then tap the Kbd button and use the keyboard to set the value to 1 and then press the OK button.
Our developers are working on this issue but due to the restrictions with the units display chipset as yet we do not have a definitive date for an updated version of Memory-Map for this unit. By using the advice on settings above and by choosing a scale of map suited to your speed (eg By switching from OS Landranger 1:50,000 to OS Road Map 1:250,000, or from CAA 1:250k to CAA 1:500k, when your speed increases) you should be able to minimise the flashing affect.
Details on when this update will be available, and what other features will be included, will be posted in this thread as soon as this information is available from the development team. Please accept our apologies for any inconvenience caused.
