This thread has been active for almost a year now, and it is time to summarize our findings and provide definitive technical conclusions regarding the use of 64-bit iGO Nextgen applications for heavy commercial truck (TIR) navigation.
Based on deep-dive community testing, source code analysis, and real-world European logistical feedback, all key results have just been structured and added directly into the first post (OP) of this thread.
Here is the definitive technical breakdown of the 64-bit distributions we investigated, with a vital focus on the ongoing confusion surrounding the AVICSYNC branch:
🛑 The AVICSYNC (v9.35.2.227616) Situation: A Dangerous Illusion
Lately, many users have been trying to force the 64-bit AVICSYNC engine to calculate routes for 40-tonne trucks, resulting in endless confusion. Let's make it clear once and for all: AVICSYNC is architecturally broken for heavy trucks.
• The HERE Maps Trap: The AVICSYNC routing engine was originally designed by NNG under an OEM contract specifically for Pioneer AVIC passenger multimedia systems and campers. It lacks deep-level truck toll matrix licensing. When you enable "Toll Road Avoidance" with HERE maps, the engine cannot process mandatory electronic truck tolls (like Germany's Toll Collect or Poland's e-TOLL). It treats these entire mandatory networks as physical "road blocks," producing absurd 2,000+ km detours. There is no magic sys.txt tweak, no missing license, and no automatic map converter that can fix this closed engine logic.
• The TomTom Maps Danger: Some drivers mistakenly celebrate because switching to TomTom maps eliminates the 2,000 km loops, creating a "nice, short route." Beware: this is a lethal trap. The easily cracked AVICSYNC binary simply blinds itself to TomTom's heavy truck physical restrictions layer (weights, dimensions, ADR). It routes a 40-tonne truck exactly like a small passenger car. Driving with this setup in the EU will inevitably lead you under a low bridge, onto restricted weight-limited roads, or into massive BAG fines.
🛒 The Basar (v9.35.2.262743) Status: Restricted easy routing
Similar to AVIC, the Basarsoft branch is a regionally locked, passenger-car-oriented core. As experienced members have correctly pointed out, even if .ftr files show up as active (green/white) in the content menu, the engine executive code is prone to silent failures. It regularly messes up heavy truck restriction tables and toll logic, making it highly unreliable for serious commercial international driving.
🟢 The World (v9.35.2.252374) Verdict: The Only Stable 64-bit Choice
If you are running a modern 64-bit Android device and need 100% reliable heavy fleet logistics, iGO Nextgen World 64-bit remains the only viable and verified solution. Its global, unrestricted core native algorithm perfectly processes multi-layered HERE .ftr data and calculates optimized, safe, toll-free routes while strictly respecting every physical boundary of a 40-tonne vehicle.
