I am just wondering would installing a different unit of HU would void the warranty or not? Coz' I intend to fit a reverse camera as well, coz' my wife is not very good in reversing car~~ especially big one life the NF
I'm not sure if it voids the warranty, my warranty is expiring in another 1 months time and don't have to deal with the issue so far. If you are a DIY guy, it takes < 30 mins to put back the original HU once you are familiar with the installation process - in fact that's what I plan to do if my steering wheel audio control button is confirmed to be faulty.
For the reverse camera, you can try to search ebay (US) for a custom made reverse camera which replace/integrated into one of the number plate light, I think it costs around US$37 shipped.
Today saja call to Hyundai checking for NF stock and they told me that 2.4 model has already out of stock, only left 2.0 white color. And all of them are in KL area. The salesman can help arrange delivery of the car from KL to Penang.
In fact, Hyundai Prai got about 8 units of While Sonata NF 2.0 and managed to sell 4 of them, and the remaining 4 were shipped back to their HQ about 2 weeks ago. I was told they were disposing them at ~ RM20k discount.
