Well if you are looking for something cheap, then head down to Nilai 3, there is one shop that sell 2 din unit that fit in Prevé, perfectly. Cost rm895. If you want to add in HD camera add another rm300. Price inclusive of installation.
Whilst I was there I saw they install the unit into one red preve, and sound is ok, they also able to map the steering buttons to the Hu. Sound wise with stock is more then acceptable, and to my ears better then stock Hu, most probably due to higher power output from this unit.
GPS uses papago as standard on window ce unit and uses malfree maps, so You can update the map for free.
They also have the branded unit Kenwood etc. On display. So you can listen in to differentiate the differences and try out the interface.
Really tempted to put in my preve but as mine still waiting for the auto rain sensor unit repair I will not touch any of stock wiring for the moment.
okey bro. shall go check out. mind to share the shop name and address as im from sk and not much exposed to Nilai areas. amd the rm895 u said was what brand bro?
