Thank you for viewing. Instant purchase without comments is OK. Currently on sale, but the price will return to the original listing price of 6900 yen at the beginning of next week, so please understand. This is an Alpine navigation system, VIE-X07B. I confirmed that the HDD powers on and plays music, but I have not checked the detailed functions, so please purchase with the understanding that. Songs are saved on the built-in HDD. Please delete them if you don't like them. Since I haven't checked the operation after removing it, it is considered as junk. We do not offer any warranty or returns after purchase, so please understand.
