I purchased one of these head unit off of eBay worked perfectly fine for 7 months then started draining the battery , got in touch with the people I brought the head unit from , what a nightmare over 50 emails with had to wait 24 hrs for a reply !!
Head unit had a uk 2 year warranty only for them to email me asking for more money , in the end settled for £100 don't buy one of these unit they won't last long !!!
