7" Chinese Gps lags for a while then crashes

[turkz1]

Hi guys

I'm running an old cooy of bazzle's 8.3.5 on in dash unit and it works beautifully. I recently purchased a 7" chinese portable unit from hong kong for moving between other vehicles and i copied the exact same file over and the gps is lagging to a point where it can't even follow my vehicle on the map and eventually comes up with the out of memory error. Is there something wrong with the device or can I just tweak the settings to maybe a lower resolution or less detail so the device can run them?

Unfortunately its prob is the 64mb internal memory that is the main issue.
Some of those unit have settings to change system/background memory use with a slider.
Also with igo try disabling some features then adding them back until it fails to see what you can live with.

Ie, POI, DEM, TTS

You could search for i3 Primo
That normally works on low mem units with not too much trouble.

You also should set/modify some parameters in section [debug] of file sys.txt as shown next:

[debug]
; how much memory should be left free (in Bytes) ?
; if you set the parameter "reserve_memory" lower than 1500000 Bytes, iGO will trump
; your settings and automatically reserve 4000000 Bytes for "other applications"
reserve_memory=1500000
cache=2048
; how much memory can take iGO (in Bytes) ?
; checked the available memory with resinfo.exe : ~50MB => 52428800 Bytes
; subtract "cache" and "reserve_memory" of it in order to get the maximum amount of memory alloted to iGO
max_memory=50926752


FYI: A fully commented sys.txt you can get from
