I currently have a pioneer deh-p9300 and was goign to change it to a newer pioneer. the dehp5800. I was wondering if i would need a wiring harness since i have the original one already in the car. I check already and the aux piece i have on the 9300 would fit the new one. Is there anything else i would need. Thanks

ps. one more thing if you could answer. How does the tv tuner work on this car. would i be able to connect a antenna behind the pioneer system to get a signal. I currnety have a tv tuner in my car but the reception is horrble. how could I improve that. Thanks

 

Should be a plug and play. That tuner should be in a location so it can get a good signal. Under the dash in not one of those places
