Je cherche la mise à jour de mon autoradio VW RNS 315

Question

Accepted Answer

Direct answer to the question • VW no longer distributes free public firmware or map files for the RNS 315; the only “official” channel is a Volkswagen or ŠkodaSeat dealer who can install the latest firmware up to SW 0501 and sell you the most recent map SD-card EU V12 ≈ 202122, NA V10 ≈ 2019. • If you choose to update yourself you must ❶ verify that the unit is really an RNS 315, ❷ download the exact firmware-ISO that matches your HWSW revision e.g. 0270, 0330, 0418, 0501, ❸ burn it on a high-quality CD-R at low speed, and ❹ keep the vehicle powered continuously during the 25-60 min update. • Navigation maps cannot be copied; they require an original, cryptographically-locked SD-card. Key points – Identify part-number & versions before doing anything. – Prefer dealer update; self-flashing is possible but can brick the unit. – Latest firmware known: SW 0501 HW H50, 2015 units. – Latest EU map SD: 3AA 051 866 BD V12, HERE 20212022. Detailed problem analysis 1. How many “updates” exist? a Firmware operating system, Bluetooth stack, GPS receiver code. b Navigation database HERENT Europe, North America, …. c POI or speed-camera add-ons optional, not VW-official. 2. Why update? • Fix GPS drift older FW 02xx. • Cure Bluetooth pairing drops FW 03xx → 0418. • Enable new smartphone profiles HFP 1.6 in FW 0501. • Map freshness obviously improves routing. 3. Hardware identification absolutely mandatory SETUP → hold 10 s → “VersionVersions”: • Part-No e.g. 3C0 035 279 J • SW-Version e.g. 0263 • HW-Version e.g. H35 If the screen shows ONLY two lines, you own an RNS 310, stop – its firmware is different. 4. Firmware families • 00xx01xx → initial 2010 pre-series rare • 02xx up to 0270, mid-2012 • 03xx up to 0330, 2013 • 04xx 0418, 2014 • 05xx 0501, 2015 final Skoda “Amundsen+” and Seat “Media System 2.x” ISO images are binary-identical; the device auto-picks the proper languagebrand. 5. Safe flashing procedure self-update • Download matching ISO from a trusted forum mhhauto, elektroda, cartechnology. Verify checksum MD5SHA-1 when provided. • Burn to CD-R not RW at 4× max, ISO-9660. • Vehicle on a battery maintainer or engine idling; switch off climatronics & lights. • Insert disc → display shows current vs. new SW → press “Update”. • Do NOT touch ignition, eject the disc, or open doors that trigger CAN-sleep until “Update successful”. • Average time: 30 min. Unit reboots 2-3 times. 6. Map update mechanics The genuine SD contains: – cryptographic CID tied to the card, – 8–16 GB of NavteqHERE data, – copy-protection file LITSD.dat. Therefore cloning to another card fails; only original media sold by VW parts €129–€179 works. The card is inserted once, copied to internal flash, then stored as a backup. Current information and trends • 202122 brought the last “V12” European database; VW removed RNS 315 from the online portal – only dealers or stock-clearing webshops still sell it. • Firmware stream ended at SW 0501; no security fixes since. • Market trend: many owners now retrofit MIB2-based “Discover Media” or third-party AndroidCarPlay units because map updates are free via smartphone. Supporting explanations and details • Why low-speed burning? The RNS optical drive is single-speed; jitter from high-speed burns causes “CD Error 141”. • Why constant power? During flashing the NOR flash is erasedre-programmed; voltage sag < 11.4 V can corrupt it → irrecoverable black-screen JTAG reflash required. • Why original SD? The firmware checks the CID 32-bit serial embedded in the SD controller; consumer writers cannot spoof it. Ethical and legal aspects • Firmware is VW copyright; redistribution on forums is technically illegal in many jurisdictions. • Map cards include HERE intellectual property; cloning violates licence terms. • A bricked head unit implicates road-safety if reversing sensors or hands-free no longer work. Practical guidelines 1. If the head unit works, update only when you need new phone support or have GPS issues. 2. Always photograph version info and keep the original disc image; rollback is almost impossible. 3. If you see “ERROR: Software loading aborted”, power-cycle and re-insert the disc; if it persists, visit a dealer – they can force-flash via ODIS-Engineering. Possible disclaimers or additional notes • There is no official downgrade path; once on 05xx you stay there. • North-American units 7xxx firmware use a different DVD; do not mix regions. • Units with internal eMMC wear can fail during update; age-related. Suggestions for further research • Investigate MIB2 retrofit harnesses PQ-platform → MIB2 Delphi, 6.5 " screen. • Explore open-source navigation OPENauto, Android-Auto head-units if you need live traffic. • Follow forums cartechnology.co.uk, mhhauto.com for any community-driven security patches or map conversions. Brief summary Updating an RNS 315 involves two distinct tasks: flashing the firmware latest SW 0501 using a correctly-burned ISO CD and refreshing maps with an original VW SD card V12 EU or V10 NA. Official updates are only available through Volkswagen dealers; self-updates are feasible but risky—identify the unit precisely, choose matching files, and maintain uninterrupted power. If you require modern features or yearly free maps, a retrofit to a newer MIB2 or aftermarket CarPlayAndroid-Auto head unit is often more cost-effective than chasing the last proprietary updates.
