Primary role: "Where is there a campsite / fuel station / mechanic near me?" This is your Africa-specific POI database — no other app comes close for overland-relevant information. Toggle categories on and off (camping, fuel, lodging, services, parks) to see what's nearby. Tap a pin for details, contacts, facilities. Not a routing app — it shows your position on the map but doesn't give turn-by-turn directions. Use it for planning and discovery, not active driving navigation.

Map updates: You carry all T4A country guides and maps — the full Africa set. Maps update quarterly. Check for updated versions over WiFi periodically. Storage: ~1.2 GB total for all Africa.

Primary role: Off-road navigation, track recording, and topographic reference. Download map tiles for your planned route area before leaving cell coverage. Multiple map sources available — OpenStreetMap is the best for African rural roads, satellite imagery is useful for route-finding in trackless areas. Record your track as you drive — this creates a GPS breadcrumb trail you can follow back if needed, and can be shared with other overlanders.

Key features for overlanding: Drop waypoints at key points (turn-offs, water sources, good campsites). Import GPX tracks from other overlanders. Measure distance between waypoints. Display coordinates in any format (decimal degrees, DMS, UTM).

Tip: Download map tiles at the highest zoom level you'll need — lower zoom downloads cover more area but show less detail. For off-road driving, download to at least zoom level 15. Budget 1–3 GB per country depending on area covered.

Primary role: Tar road routing between towns with turn-by-turn directions and ETA. Download offline areas for each major route segment before losing cell coverage. Each offline area covers a region roughly 100 × 100 km at useful detail. Download multiple areas to cover your planned route.

Limitation: Offline areas expire after ~30 days. You'll need to re-download when you next have WiFi. Google Maps has almost no data on dirt tracks, 4×4 routes, or campsites — it will try to route you on tar even when a direct dirt road exists. Never use Google Maps as your only navigation tool off tar.

Primary role: Always-on dashboard navigation with T4A routing. Permanently mounted on the windscreen and wired into the 12V socket — it has essentially no internal battery (~30 seconds). It uses its own GPS chipset (doesn't drain your phone), and the T4A maps provide Africa-specific routing including gravel roads and 4×4 tracks that Google Maps doesn't know about. If the vehicle's 12V cuts out, the Nuvi dies immediately — your phone becomes primary.

Map updates: T4A GPS maps are subscription-based (annual). Download the latest version to a micro-SD card and load into the Nuvi before the trip. New map versions release quarterly (currently v26.03, March 2026). Update procedure: download from T4A website on your computer, copy the .img file to the Garmin's SD card.

Backup role: If your iPhone is lost, stolen, or broken, the Garmin keeps you navigating — as long as the vehicle's 12V is running. Because the Nuvi has no meaningful internal battery, your phone is actually the backup if the vehicle electrics fail. This is why both devices matter.

Thuraya XT-LITE (~R15,800): Cheapest option. Covers all of Africa, Europe, Middle East, Asia. Compact, lightweight. No SOS button or GPS. Good voice quality. Cheapest airtime plans. Best value if you only need Africa coverage — which you do.

Inmarsat IsatPhone 2 (~R22,000): Best battery life (8 hrs talk, 160 hrs standby). IP65 rated. SOS button with GPS location. Covers everywhere except poles. Very reliable — the workhorse sat phone used by NGOs and aid workers across Africa. Recommended if budget allows.

Iridium 9575 Extreme (~R36,000): True global coverage including poles. MIL-STD-810 rugged. SOS with GEOS. Most expensive handset and airtime. Overkill for your route — you don't need polar coverage.

Buy a local SIM in every country. This is by far the cheapest way to get data and voice. A local SIM with 5–10 GB of data typically costs USD 3–10 and lasts 30 days. With a local number you can make local calls (arranging campsites, mechanics, border info) at local rates. Your iPhone must be unlocked — verify this before the trip.

Where to buy: At the border (vendors often sell SIMs right at the crossing), at the first town's mobile operator shop, or at the airport. Major operators: Vodacom/MTN (SA, Tanzania, Mozambique), Airtel (across East Africa), Safaricom (Kenya), MTN (Rwanda, Uganda, Zambia). You'll need your passport for registration in most countries — this is mandatory and they won't activate without it.

Tip: Keep your SA SIM active (put it on the cheapest plan or pay-as-you-go) for WhatsApp verification and banking OTPs. Use a dual-SIM phone or carry your SA SIM in a small holder.

Travel insurance emergency line: Save both the local and international number. Test that it works from your sat phone before the trip.

SA Embassy contacts: For each country on your route, save the SA embassy/consulate phone number and physical address. Cross-reference R15 (Border Crossings) country cards.

Medical evacuation: Your insurance provider's emergency evacuation coordinator. Also save ER24 International (+27 10 205 3068) and Netcare 911 International as backups.

Vehicle recovery: Save AA of SA's international number. In practice, local recovery is arranged through your insurance or by calling a local contact — but having the AA number gives you a starting point.

Family contact: One designated person at home who knows your route, has your insurance details, and can coordinate on your behalf if you're incapacitated. Share your InReach tracking link with them.

iPhone: The biggest power consumer. GPS + screen + navigation app = flat in 3–4 hours. Plug into the 12V charger whenever driving. Use the Garmin Nuvi as primary dashboard navigation to preserve phone battery. Turn off WiFi, Bluetooth, and background app refresh when not needed. Enable low-power mode when off the charger. Carry a 20,000 mAh power bank as backup — charges the iPhone 4–5 times.

Garmin Nuvi: Permanently wired to 12V — has essentially no internal battery (~30 seconds). If the engine is running, the Nuvi is running. If the vehicle electrics fail, the Nuvi dies. This means your iPhone (with its own battery and power bank) is your true emergency backup, not the Nuvi.

Sat phone: The IsatPhone 2 has outstanding standby life (160 hours). Keep it off unless you need to make a call or are expecting one. Check it once daily. Charge weekly or as needed.

InReach Mini 2: In 10-minute tracking mode, battery lasts ~3.5 days. In 30-minute tracking mode, ~7 days. In expedition mode (1-hour intervals), ~14 days. Charge via USB when driving. The InReach's power efficiency is one of its biggest advantages over a sat phone for always-on tracking.

Charging: All devices charge via USB. The vehicle's 12V system (or future LiFePO4 auxiliary) feeds a multi-port USB charger on the dashboard. Carry two chargers (one in the cab, one at camp) and a quality multi-cable. Cross-reference R5 (Battery Training) for auxiliary system details.
