VP4 Harman Navigation Radio Repair (2011 to 2018)

Send us your unit, we repair it, you plug it back in

If the Harman navigation system in your Jeep, Chrysler, Jeep has stopped working, Module Medics can fix it. We specialize in repairing factory VP4 Harman infotainment and navigation head units, restoring failed units to full working order with a professional bench level repair.

Your original head unit is married to your vehicle VIN. That means a used unit from another car cannot simply be installed in yours. To run a replacement unit you would normally have to visit the dealer for online coding, a software update, and the installation of every license file tied to your VIN.

Repairing your original unit skips all of that. You get your own unit back, fully repaired, already coded and programmed to your VIN, with no extra steps. Plug it back in and drive. That is the whole point of our service: you ship us the unit, we repair it, and we send it back ready to use.

Common part numbers affected

The numbers below are commonly seen on VP4 and RA4 8.4 inch Harman units and on the earlier RHB MyGIG High units. Suffix letters such as AA, AB, AE, AF, AG, AH, AJ, and AK indicate hardware or software revisions and are all candidates for repair. Your number is printed on a label on the unit itself, often starting with a "P" prefix.

• 68270661 (AE, AF and related revisions)
• 68312543 (AD and related revisions)
• 68190240 (AB, AG and related revisions)

Please note: this is not a complete list. There are many more part numbers and revision codes than we can list here, and FCA released numerous superseding numbers over the production run. If your part number is not shown above, that does not mean we cannot help. Send us the exact number from your label and we will confirm fitment and repair coverage.
